There was an op-ed piece in The New York Times by an evolutionary biologist or somebody - which was a curious place for the opinion to come from - and he said that there's no such thing as a completely free, uncensored medium, that people censor themselves all the time, in deference to hurting other people's feelings, or offending other groups, or in their own, not to provoke a fight. And you do self-censor certain things, and it's not necessarily a bad thing. That's just the way human social interaction works.
