It is not Hitch that used hateful words but Scripture in multiple places and Paul in his letter to the saints in Rome uses it.
It is Scripture that says, they are fools (Rom 1:22)
It is Scripture that says, they are without excuse (Rom 1:20).
It is Scripture that says, they will never inherit kingdom of God (1Cor 6:9)
It is Scripture that says, they are deserving of death (Rom 1:32)
It is Scripture that says, vengeance of eternal fire is upon them (Jude 1:7)
It is Scripture that says, not to pray for people who do sins leading to death (1John 5:16)
It is Scripture that says, God abhors them (Lev 20:23)
So, gays are fools without excuse who will never inherit Kingdom of God but deserving death and vengeance of eternal file is upon them for whom I need not pray and God abhors them.
Anyone having His Spirit will never love such a person because, God abhors them. If we do not abhor who God abhors, then His Spirit is not within us.
No you don't use hateful words.
