Calling out bigots and assholes isn't "feeding." That's the problem. Telling people to ignore outright bastards just leads the bastards to escalate. You should absolutely identify their bullshit and bluntly tell them where to shove it - and more importantly, forums need to allow calling out bullshit.

Any moderator demanding "respect" and "civility" is creating an environment where cautious monsters have free reign, unless they also proactively fight politely-phrased abuse. If someone has good reason to say "fuck off," and you remove the response but not the cause, you are a force multiplier for that abuse.

But this schmuck? Yeah, ignore that. It is of low quality.
