So What is it that I don't understand? Seems pretty straight forward to me.
First, I'm glad I'm not a masochist. Second, the rest of your post is just you making claims of what other's think and projecting your views over something that is simple. Dan is pointing out things in the Bible we don't follow anymore, like slavery and levitican Law, and explaining how Christianity and US culture has left those things behind and how eventually people will do the same with LGBT. The people probably left because he dared to point out the obvious to anyone who has actually read the Bible and know the basics of US history.
Here is something I can address with you, to address what it is that you are misunderstanding, and I promise to practice respect and humility. Something I'm trying to work on.
Where non-Christians, like Dan Savage, are misinterpreting the law and the bible is in not understanding the different views and distinctions of the law within the Judeo-Christian view, and knowing how "non-Christians", fit in that view.
If you will allow, let's take a look at the law, and Dan Savage's message against the Judeo-Christian view. I'll break it up into two parts.
A) The first distinction of the law is that while all mankind is condemned under the law, non-Jews and non-Christians are not held to the law as Christians and Jews, because they are already condemned. There is no salvation for the willfully un-saved, or non-elect under the law.
As non-Christians they represent themselves. They will say they are a good person. What they don't understand is they represent themselves against the law of God, not on behalf of God's law, which they also use to say they are good, even if they don't believe in God. They are convinced the law is simply man's law, and since this is the case, they strive to effect man's law. And so, they are working to legalize their own sin under man's law which will allow them to not be guilty under man's law, unaware they, like all men, are guilty of all of God's law. This is the first part of what is not understood by non-Christians.
It should be noted that many Saved - Christians hold to the belief that they also represent themselves to some degree under God's law. However, their condition as saved distinguishes them from the non-saved in terms of being condemned under the law. They are saved and represented by Christ.
The irony of Dan's message is that he thinks he's inclusive to the law of Leviticus in talking about shellfish and homosexuality. To further point this out, let's use your quote.
"Dan is pointing out things in the Bible we don't follow anymore." We? Who's the we? non-Christians, like Dan, are thinking they are the we, in that Leviticus was speaking to all mankind in the same way, and It's not.
Dan is not Jewish, or Christian. The un-saved are outside the law as such, but the law applies to the un-saved in that they are condemned under it by nature. All mankind is condemned under the same law, but held to it differently. Hold that thought and keep reading please.
B) There is a distinction in the law between civil law, ceremonial law, and moral law.
Jews side, There are some differences within the Christian faith on what is held and what is no longer held in terms of the law, but the differences are not divisive to the faith itself.
Rather than describe each view in detail, I'll list the title distinctive views on the law, and you can research them on your own. I will focus on the reformed view because that's the one I hold to the most. Here they are. Roman Catholic, Lutheran, Reformed, Anglican, Dispensationalism, Theonomy, New Covenant Theology, Dual-covenant theology, Torah Submission, and Jesusism. Each one of these view see the law and the covenant between God and man differently, but there are similarities that bond them together.
You'll notice I did not list the Atheist view of the law, or the non-Christian view. As I addressed in point A) above. There is no "WE" in Christianity, and all of mankind when it comes to the law of God and what's allowed. Although some will say you go to hell for this or that, The gospel points out that all are condemned under the same law, and if you are guilty of even part of it you are guilty of all of it.
The view of the Reformed churches, referred to as Covenant Theology, is similar to the Roman Catholic view in holding that Mosaic Law continues under the New Covenant, while declaring that parts of it have "expired" and are no longer applicable. However, the Westminster Confession of Faith (1646) divides the Mosaic laws into three categories: moral, civil, and ceremonial.
In the view of the Westminster Divines, only the moral laws of the Mosaic Law, which include the Ten Commandments and the commands repeated in the New Testament, directly apply to Christians today. Ceremonial laws, in this view, include the regulations pertaining to ceremonial cleanliness, festivals, diet, and the Levitical priesthood, which do not apply to Christians in the new covenant. Homosexuality falls within the moral law, where as shellfish and slavery fall into ceremonial and civil law respectively.
Because Jesus fulfilled the law, there is no need for the civil and ceremonial laws as they where largely an antitype of Christ. These are sometimes referred to as "types and shadows" of Christ to come. Gods moral laws are observed by mankind through Christ in those who are in Christ, and they are discounted by mankind by those not in Christ. Part of that, is also displayed in man's societal law.
In this view of the law overlap between categories does occur, the divisions they make are possible and supported based on information contained in the commands themselves; specifically to whom they are addressed, whom or what they speak about, and their content.
For example, a ceremonial law might be addressed to the Levites, speak of purification or holiness and have content that could be considered as a foreshadowing of some aspect of Christ's life or ministry. In keeping with this, most advocates also hold that when the law is spoken of as everlasting, it is in reference to certain divisions of the Law, which I have just explained in sort.
We are living in what can be described as a post Christian society. A society that has pushed back on Christianity and it's influence within social/cultural institutions, like education, health care, marriage and family, welfare, government and law. This has been taking place for a long time.
It's already made huge influences in education, welfare, government, and it's moving into marriage and family, with it's eye on healthcare. The goal of the world is to de-Christianize these institutions in every way possible to exclude God as much as possible and replace God as God with man as god.
To further explain this; from a biblical prospective Satan rules the world, and one of the best ways for him to do that is to influence and effect that which mankind is most concerned with; his own self preservation, and ignorance of his own condemnation in his inevitable death. What Satan knows is that the unregenerate will not concern themselves with this fact and would rather just live pleasurably while they are alive then to contemplate their own destiny. As he said to Eve in the garden, Gen3:4 "You will not certainly die," the serpent said to the woman. 5 "For God knows that when you eat from it your eyes will be opened, and you will be like God, knowing good and evil." ................Dan Savage saying the same thing, but only under different circumstances. If you had to place a face on Satan and his message in todays world just look at that video.
When it comes to the law and the gospel the un-saved, (those who reject God) have an advantage to speaking on what they don't fully understand. They can make a few remarks and sound knowledgeable among each other without realizing the ignorance of their own biblically illiterate statements. Dan Savage points this condition out clearly in his own remarks where he says; "We can learn to ignore what the bible says." The word ignorance is a derivative of the word "ignore", but again, who is he talking to when he says "we"? It's not the Christians; It's the lost in an effort to rally them against God.
