No. The best thing is to use time brackets to minimise the chances of minors viewing damaging stuff, and to mark the start of each show with a clear list of warnings for specific types of content. That way, adults can make their own choices.
Some things do need to be censored. I'm against explicit scenes of child-pornography, rape, racism, violence, torture, drug abuse and crime. These themes do need to be dealt with as a means of discussing the realities of the world, how and why they occur, and to explore the solutions - but they do not need to be shown in ways they would excite or incite sociopaths.
