Agreed, some men have valuable input. E.g. I am an expert tampon buyer. And I have coached a woman or two. Many men have. In fact I bet there are dozens of men who have trained women professionally for every one woman who has trained another woman.
The problem here now is the bizarre enforcement of the rules. Technically I'm not even allowed to post this (didn't request permission to post!). But I'm almost sure it will stand, as it is positive and doesn't step on any toes. Then again if I post something that isn't rabidly feminine (or sucking up to feminine mores in general) then the post gets deleted 'because I didn't ask permission to post'. That's bullshit: a rule exists or it doesn't. And if it exists it should be enforced consistently, without personal prejudice.
I think men are fine with moderation. There are many subfora here that are all knowledge, no flaming. The AAS board is just one great example: some of the biggest users, but no roid rage. The nutrition section is also fine.
In my opinion you need responsible moderators, who moderate based ONLY on rules, not personal preference. Factual disagreement or clearly labelled personal opinions should be allowed, even from men. Not allowing normal discussion has turned this section into the perfect stereotype of what men think of women: 'women talk, men are supposed to sit back and shut up'. Well, it's clear how well that strategy is working...
