It seems to me that a truly 'healthy' community would not draw it's boundaries so tightly.
If I were building a community I'd want it to be one that welcomed even those with views I found despicable so long as they could engage in thoughtful, reasonable discourse. A community should allow for people to be wrong, and still be welcome.
