Suppressing racist speech is also censorship, so it seems like you're actually affirming the parallel. Since you seem to think it's self-evident that racist content should be banned and equally self-evident that this content should not be, why don't you tell us where the line is? This is very fine line to walk — you will anger somebody no matter what you do — so if you have any insights, I'm sure the people faced with the decision will appreciate them.
