I just tell leftists I don’t buy that they are “pro-gay rights”.
“Gay rights” is simply a cover for the left to criminalize the Christian beliefs that they despise. They are anti-Christian bigots who are trying to put themselves on the side of the angels by claiming a bogus pro civil rights position.
Oh, they’re on the side of the angels (the fallen ones—remember Colossians 2:18), but not on the side of God.
