It's just place where you can be pessimistic by default. It's forgotten everywhere else it seems.
There can be an acceptance that things are too far gone for most people to impact positively, and that many people have consigned themselves to this. IMO as long as they aren't going out into public and trying to attack environmentalists who are trying to make changes, it's a good and healthy thing for people to have a community of like-minded individuals to talk with.
