I think that there are some people for whom P&P is the center of femslash fandom, you know? And I think that those people have kind of forgotten that their experience =\= everyone's experience. It's also been around long enough that it has a pretty prolific core group, and some of that core group gets rather defensive of critique. Which irritates other people. Which leads to the vitriol that comes out on anon posts (from the pro-P&P and irritated-with-P&P groups both), I think.

(I think that, once the commentary on this post dies down, we'll be having another anon post. I love those.)
