Again, people can revile all they want, but if they say they are doing so under the guidance of God's word, that is blasphemy. So-called Christians use contemptuous language to describe their gay neighbours and use misquoted texts from the Bible to justify refusing to do business with them. This is a sin on par with being a catamite, as cited in your post. If they were actually adhering to their religious belief, they would love their neighbour and let God judge them.
