Banning users and deleting discussions (Reddit) or even moving them (BCT) solely to reach some political goal is not 'so called "censorship"' it is the very definition of it.
Moving threads is not the definition of censorship.
I will not talk about reddit. Bitcointalk.org is a privately owned forum, i.e. theymos is letting you talk about A LOT of things in his backyard. I'd say for sure that 99% of your guys have minimum experience with forums. Quite a lot of admins would instantly ban you for even accusing them of censorship or similar stuff. Theymos is really tolerant.
Moderation has been lighter here than on Reddit, that's true. (I've only had two of my posts deleted and nothing particularly important) But it's hard to know full extent of it. As much as I disagree with Theymos' position I don't think he's lying and it's time for me to move on to somewhere where the moderators wont actively try to sabotage the discussion.
Then go ahead. If someone does not like the rules (which are pretty good in my opinion), they can either: A) Respect them; B) Leave. A lot of people have complained on various things and said that they would leave, yet almost nobody ever did (i.e. leave for another forum).
Update:
Nice ninja delete. I've deleted my previous post because of it.
