Yeah - I suppose, put simply, some people are more sensitive than others. That much is plain to see from the variety of reactions re the controversial threads, so yes some kind of user-controlled filtering would seem to be in order but it must work both ways - no good asking not to be offended in your viewing but being able to send out offensive posts.
Can I have mine turned completely off though please so that I might be offended to the max ?
( There is a question on the registration for this forum that asks if your're under 13yo - is this a kind of content filter ? )
