I'd get rid of political parties if I could, but I also think it's basically impossible, so the question then becomes how you deal with them. The best way to deal with them may not be at all how things would look if you could get rid of them. That's how I go from wanting to ban them to proposing proportional representation.
Fair enough. I prefer to think about what can be done to reduce their influence. I wouldn't actually ban them even if I could, freedom of association and all that, but it would be nicer if they didn't matter so much.
