I don't think that too, but we can't expect everyone on the right to be perfectly righteous. Humans are flawed. What we are after is s society which has our values backed in, not a city on the hill full of saints. Not even the Roman inquisition was after the private heresy, it was a crime only if heresy was actually preached to others.

Edit: without external influence most people isn't even interested in tranny porn at all, because sex with women is better. The problem is the societal promotion of such behaviour, not the single act by itself.
