Moderation and censorship are radically different.

Moderation is just to prevent spam and personal attacks and things that have no connection to the conversation.

Censorship is manipulating the conversation by removing ideas that go against the conversation even if they are relevant, well sourced, and respectfully presented.

Be sure not to get the two confused.

The difference between censorship and moderation is entirely subjective. Censors always think they're moderators — that they're protecting the quality of the discourse rather than stifling ideas they dislike — because part of how they rationalize their dislike of those ideas is by believing that they harm the discussion.

I think there may be some grey area but a moderator vs a censor are very different.
