@RainierBeringer That and when I think of 'local justice from the community' I always associate it with things like Charivari which are, yes, the community coming together to enforce community norms, but in these case the 'norms' involve harassing gay, asexual, or just plain infertile people or folks who have otherwise done something that's none of anyone else's business.
There are reasons I think a systematic, formal baseline and something of an enforced independence between how people can treat others based on various aspects of their lives are important and get really suspicious when someone says 'Oh, we just need close, respectful communities!'
