I believe you should take that stuff on directly, not hide from it. By repeatedly beating down the zealots publicly, using logic and reason, you will sway the people who are impressionable. By secluding yourselves from what you see as hateful, you are letting it run free unchallenged.
If this place allowed all sides of a political issue, even the racist assholes, you could destroy them on any issue.
The rise of the Alt-Right has been allowed by the seclusion of the liberals into their safe spaces. Don't get me wrong, I understand why you don't want those people here. They say stuff that can be hurtful, but we have to be stronger than that and unafraid to debate them head on. Hiding won't make the alt-right, or the ridiculous ideas of Republicans, go away.
i think croatoan is right. he should start by going to the donald and breitbart comment section to beat zealots off with logic and reason regarding climate change. if they can't come to neogaf, he must go to them
