First of all, a hug from far, and may the alienation go away soon.

Second, I've found there's no point in discussing politics with people. Not with friends, not with strangers. There's no point in trying to find people 'aligned enough' with my political ideas. Since I've accepted that I feel that my attempts at spreading anarchism lead so much further! As long as I never mention the word (or any other political jargon), and always, always approach my fellow humans as humans and try to inquire about what moves them, not tell them what I think they should do.

What do you think is missing in your neighbourhood? If you think it's human contact, try to start there and invent ways to encourage friendly contact. Maybe create a point for food sharing or book sharing. If people are too shy to speak to each other in person at this point, give them other options, so they can lose their shyness gradually.
