The boxes shouldn't exist, unless they were to define people as they relate to specific issues. I have been raged at for being a "liberal" because users assume I subscribe to many views which I definitely do not. They even go as far to tell me I'm wrong about what I believe because "you're a liberal!!" Which I'm not, insofar as how they mean it. And that's the problem.

To continue the analogy. You say you're putting boxes on the shelf and people climb into them. I'd compare it more to people looking at the box labels and then you're shoving them into the boxes just for that. It's all oversimplified and kills conversations and progress. The fact that I strongly want an end to many social problems which could be addressed by universal healthcare and regulating capitalism means nothing to most of these label-oriented users. The only people who aren't evil capitalist pigs are those who fit their same label. It's actually sick, disgusting, and counterproductive. It's exactly what you'd want if you're a billionaire. People who want mostly the same things hating and icing each other out.
