Who said anything about censorship? I said there are plenty already, so people can make whatever movie they want, but I just don't see the point of covering topics that have already been covered to death with no real fresh perspective. "Sweeping it under the carpet" isn't even a option, and wasn't suggested. I'd be more interested in a movie that doesn't rely almost entirely on footage from over half a century ago, and think that would be more relevant.
If such a large part of the world sees America as racist, why the fuck do so many non-whites want to move here more than any other country? Their mouths say one thing, but their feet say another.
