Every community united by similar attributes, predetermined by society, is striving for it's best interests. Noone wants to be looked down upon, is it your race, gender, disability, sexuality. A community is created. To fight for your common problem.
I don't believe in communities. I believe in a singular community. Everyone caring about everybody's problems not just their own, everyone accepting everyone. But maybe that is just because I haven't found a community to be part of. Who else despises the world so much to want it destroyed? Who would accept me
