No one was censored, and speech is only free when it's in a public place.
Perhaps you need to read a bit about what censorship actually is. At the end of the day, we want to discourage the members from acting like asshats. The longer we're open, the more effort that requires, because people abuse the freedoms they're given. The "head-fi" thing to do would have been to make it disappear, and ban anyone who brought it up. What we've done instead is point out that it was an immature thread, and an asshat thing to do. You don't like it, fine, we'll let you bitch. If the bitching gets out of hand, that thread will probably get closed too. Sometimes even posts are deleted, editted, or moved to private areas. But it's really rare, and we'd rather not do those things.
