Doesn't censoring stuff like this rather than broadcasting intact along with disapproving commentary actually work against any positive social change taking place? I mean that's creating a venue where mobs of people can be as openy racist / homophobic / etc as they want and it will be quietly hushed up. Sweeping the truth under the rug doesn't solve anything, it just festers in the dark.
