I'm actually more sympathetic than the average libertarian to marginalized groups, because social marginalization itself is a terrible thing and it seems hard to address without some sort of community-oriented focus that goes beyond conventional "libertarian" politics and its focus on mere individual equality.

However, I also thinking most advocacy is falling way short of acheving stronger community ties for marginalized groups. Indeed, a lot of such advocacy is clearly counterproductive, in pushing for "liberal" social atomization and further marginalization.
