It is pretty evident that there is absolutely no way to please everyone all the time - or even most of the time, so the obvious fall back position is that when a site is formed and is moderated, that the owners of the site make the ground rules. They set up rules that conform to their beliefs and sensibilities.

No one is forced to visit their site or agree with their standards, nor should they be expected to conform to anyone eles's standards... unless there is jail time associated with non-conformance. ( joke here, guys)

Just as beauty is in the eye of the beholder - so is "inappropriate" language (or whatever else is being objected to. And anyone who is truely upset by some of the threads on this site is perfectly free to go elsewhere to find less "disturbing" material. Enjoy the view from your bellybutton.
