Well, you really need to pose that not to a historian but to a social worker. I'm not going to give you a very professional response to that question, but I'll give you a very personal response to it.
When I was a kid, I belonged to a local police club. This was in a semi-rural area outside of Toronto. I never got beat up so much in my life as when I belonged to that social club. Why? Because it attracted all the local toughs from the community. So I would add that there's a downside to community activities as well.
