The forum has almost 5400 posts, and right around 30 moderator actions (perhaps a handful more if you count cases where there is a mod comment, and no other action.) Generously, we're looking at 1%, in other words.
Of those, I am fairly sure that less than half of them were controversial.
While - particularly with a 'heavier' moderation scheme - it is never going to be the case that everyone is happy with moderation, I think that suggesting that there is a spirit of 'For god sakes don't open your mouth' is at best a product of focusing on the negative incidents.
On the other end, there are going to be times that people are offended by things that do not receive moderator action. Not all reports are acted on. You don't see those, though. This is how it is supposed to work.
If the moderators are doing a good job, some people are going to be unhappy. The mods might make mistakes, now and then, even - we're all only human. The community as a whole will remain healthy, though.
I would also like to point out that having a post moved to the catacombs doesn't constitute a warning (in and of itself, though depending on the situation, a formal or informal warning may also be issued), or suggest that the intent of that post was necessarily malicious. It just means there was something problematic with the post.
Generally what that problem is is pointed out by the mod who took action, and if it's not clear please feel free to ask here or in a PM. At that point, in many cases, it is perfectly acceptable to rephrase and repost. If it isn't clear in a given case whether it is acceptable, again, simply ask the mod who took action via PM, or ask here in the Moderation Section.
