The flip was equating it to perpetrating a genocidal ideology, with the same argument as used in lashing out against its perpetrators, because that's exactly the same stuff that's going through a genocidal maniac's head (or at least coming out of their mouths). But all my points stand.

It's too easy to label somebody a Nazi (or whatever label enables you), eliminate all civility and humanity from them, wish them nothing but death, and consider yourself righteous and tolerant for it.

It is better to err on the side of treating bad people with more respect than they deserve, than to err on the side of treating decent people with more hate than they deserve. Because your judgment of how bad or decent they are is at the very best based on incomplete information in the first place. Erring on the side of hate directly makes the world a worse place, and erring on the side of respect makes the world a more civil place.
