I don't do the name-calling thing but I do tend to disengage, having run out of patience long ago. In decades online I have only seen two conversions out of thousands of people, which is FAIAP zero.

But that exception strategy works. Once a bigot knows someone from the hated group to be a respectable person the whole attitude crumbles. I like to think I've been the exception a few times for gay-haters.
