Bench Seats

What the fuck is the deal with people and not wanting to share a bench seat, subway seat, train seat, or just being remotely close to a stranger. I understand that there are some messed up people in this world and you can't trust everyone but would it kill you to sit next to someone? How can any group of people have any power over our own land when we don't even trust each other? It makes sense to me that there has been so much corruption in our country because if we're divided in such stupid subtle ways we can be manipulated easily. It's so annoying to see some guy spread his legs out on the subway, claiming a whole bench just because it's kind of weird to sit next to a stranger. Grow up.
