>I think what I learned from the experience is at some point you’ve got to compartmentalize harmful people from your groups and inevitably a growing number of segments of society, even if that feels wrong in some way. It’s more wrong to let them perpetually abuse people.

You need to ban abusive people at the first possible time (after you have established that they are abusive and not, e.g just ESL who learned from an old TV show/book). The more moderation a community has, the better the community will be.

If somebody has Asbergers and can't adjust, ban them too. The why doesn't matter (unless it is easily correctable), the how does.
