With all due respect, at least at RB you can say exactly what you want without fear of getting your messages deleted, being thrown in "jail" (which, from what I have read over there, is worse than kids begging their parents to let them off restriction). At least at RB, if you don't like what someone is saying, you simply hit the ignore button. There is noone that will delete or ban you based on THEIR opinion of what is acceptable. There is noone to take sides and allow some to post freely while others get deleted/jailed/banned.
Of course, this is my opinion. However, if it doesn't agree with a moderators/admins, it will probably be deleted before you get finished reading it.
