That's not entirely true, at least with the numerous 'Self Moderated' threads you will experience first class dictatorship and hostile deletion of posts OP feels run contrary to their opinion. Honestly, I believe Theymos should expunge the privileges of self moderating threads. It's long overdue.
Self moderated threads are made to be censored.
I usually open such threads myself to insta delete comments from some people. But they know it and they usually create another thread ot answer mine.
You can say whatever you want here. Just be on topic.
