pagwatch - I don't see any evidence of a lack of equality of censorship - but this could well just be because we pay attention to different things on MN.
The only way we could determine this is for MN to release the data about what has been moderated and why - which would open a can of worms, cause privacy issues and be open to misinterpretation.
Daftpunk has been involved in some pretty offensive threads about sexuality and race.
I think the alternative to "anyone who wants to state any shit should be allowed to do so because they may, somewhere have an element of a point." is that censorship would inevitably creep in to more and more issues, as other sets of people say "Well THOSE peoples issues are protected, why aren't MINE?"
Clearly, this shouldn't apply to support forums.
Claw3 - I don't agree that it WAS discrimination, as above.
