If we talk about the political theory there's almost a mistaken notion on the left and the right about IP. They both accept the same wrong premise. Both the left, and the right believe the myth that intellectual property is a western capitalist property right. And for that reason the right wing supports it, and for that reason the left wing opposes it. (...) Problem is - they're both wrong. Intellectual property is not a type of property right. It actually goes against property rights. So once you recognize that (...) the right should oppose it, because it goes against property rights. The left is confused in this issue. Depends on which leftist you're talking about. The left libertarians are good on this issue, I have to say.
