Its not about the political victories, its about the sense of support and meaning that being a part of a community brings. If anything this hints at one of the issues of the left and its something I noticed earlier too when you tried to equate civil society with what
@Jack V Savage was talking about. Its not about being a part of a formal group like an NGO or union or something like that. Its about a shared sense of community among people with similar customs and norms.
I don't think NGOs or unions can fill the hole that a local church or extended family networks fill. On a societal level those organizations play an important function but I don't think they're as effective at generating the kind of experience that the aforementioned traditional activities do.
