JeanieK, I don't mean to be rude, but clearly you ARE offended. I posted a thread in Health a few months ago asking why my dog was suddenly getting a lot of erections, and you accused me of creating it just to "stir things up". Do you not see how rude you can be about this topic? Calling someone who started a thread pathetic and attention seeking? That's really cruel.
To me, there's an obvious reason why the thread in question is not "obscene": it's purpose is not to arouse the reader. It's a practical question on an issue many women struggle with in their marriages. Why is that so awful?
As for whether this site should be "child-safe": I would say that the many threads here express views that are not really appropriate for children. Not because they are dirty, but because they express grown up attitudes. What about the thread "What About Us?", with some very sad pictures and stories of dogs in puppy mills? That has "graphic" in the title, doesn't that also attract attention?
