Shouldn't we, the humble readers of this forum, be presumed as adults, capable of discerning which is which? Or we need a nanny for it?
The presence of this thread indicates that we are not really dealing with dangerous censorship, but more of a "time out". People with something useful to say know that they can start a new, hopefully less stormy thread after a pause for tempers to cool. Meanwhile, even as an adult, I often get driven away from a thread with useful content when I have to swallow a sand-storm of irrelevancies to get at that content. (And I have also lapsed into some sand-throwing myself at times.)
