Yes this essential biological function (the ability to discriminate) has been tainted by modern political implications and applications. I am also against this form of discrimination for even God is not a respecter of persons (meaning status, gender, ethnicity, and other such things hold no weight with Him). However, we must not throw out the baby with the bath water. Without the ability to discriminate we would as young people walk away with strangers, or even as adults walk right off of cliffs, or into the fire, and more.
Sadly humans quite often take that which was meant for good and turn it into or apply it in some evil or selfish way. When Einstein said E - MC squared, he was excited about how this would unlock the key to an endless, eventually free, source of energy (through fusion). Humans motivated by power and money and other self-oriented motivations turned it around (fission) and made the most heinous bomb ever devised.
Our Lord however is quite the opposite, and often takes that which men have meant for evil and turns it for our good.
