Coupla points.
The elitist comment wasn't in reference to this thread. It was in reference to stuff that has been said on the board in general, about feminists and the feminist section. Indeed lots of people have tried to listen to those comments and make an effort to start threads that are welcoming for posters who may not be familiar with some aspects of feminist analysis (forkful's thread and Lenin's thread come to mind).
I disagree with the notion that every subsection on MN is considered to be the same and gets treated in exactly the same way.
AIBU has been given a 'header' (I'm not aware that that was considered controversial at the time but perhaps it was, I didn't follow what went on there).
Special Needs has also been adapted in order to deal with the trolling and general nastiness that it attracted.
I'm of the opinion that when a website as big and well known as MN adds a 'special interest/specific topic' section, it is probably with the realisation that different topics present different problems and difficulties.
I remember when the vaccination topic was started and I was hesitant about posting on it because I suspected that I would get told that my child's bad reaction to her childhood vaccines was in my head. I got told exactly that and so did quite a lot of other posters. The section is also however, a great place for info and support as well. I stopped posting there in part because of the personal 'you is mad you is' level of tone that was often present. MN did swiftly ban a couple of trolls we attracted though and on the whole the section is reasonably balanced.
I'm of the opinion that the posters who were unpleasant/personal/aggressive/etc on the vaccinations topic tended to be so out of good faith. They found it really worrying that views like mine were being expressed. They genuinely felt that their children or other children were in danger. I disagree with these views but I understand the place of genuine parental concern that they come from. Indeed they were views that I once held myself.
I think what happens in feminism is a little different however and I may be being ungenerous but I think there is a fair amount of 'baiting the feminists' which goes on.
Constructive feminist discussion is often quite difficult to have (in general, not just on MN) because it is, by definition, outwith the mainstream, questioning of the status quo and questioning of the values of society at large. I think it is worthwhile discussion though and I think it deserves to be nourished in a place like MN. It wouldn't take much for that to be happening.
