To be fair. US doesn’t allow for dissemination of art that has radical values. Unless we are to consider color revolutions, adventurism and pro-militarism to be radical.

Edit: Yeah there are a lot of satirical critiques aimed at the flaws of the system, but that’s not really radical art. That just promotes ironically participating in the system. “Well shit sucks, but at least I’m aware of it, what can you do? haha”
