. WP:NOT censored states: "Wikipedia cannot guarantee that articles or images are tasteful to all users or adhere to specific social or religious norms or requirements." It doesn't state: "It is Wikipedias mission to publish tasteless articles or images and breaking social or religious norms or requirements."
WP:Profanity is more specific in that matter. It states: "Including information about offensive material is part of Wikipedia's encyclopedic mission; being offensive is not."
So, Wikipedia editors need not self-censor, while engaged in writing the encyclopedia articles. As decent people, they will self-censor in talk page discussion. Self-censorship is of course a basic social requirement.
This is comparable to the common understanding about academic freedom: you can say anything, independent of the popularity of the opinion. WP should be dealing with facts, though. In both cases, there is a clear understanding about _how_ you say things, which comes as a responsibility of the role. That is a matter of reputation-management rather than policy, though.
