You realize that this a Republican FCC and that the leading proponents of such measures are the PTC and other right-wing/evangelical-esque censorship groups?
Liberals, like conservatives, don't like what's on TV for the most part, but we tend to be viciously anti-censorship. We much prefer boycott to censorship (we also have a bigger problem with violence on TV than, say, boobies).
Yes I am aware, and it's one of the few things I don't agree with my party on and I'm with you in voting with your remote i.e. boycott if there is something you don't agree with. As I've gotten older I've decided that the further you are to one side of the aisle and rooted in those fundamentalist values you actually end up meeting your opposite who wants the same goal as you the destruction of the ideas that dissent yours.
