Yes, I was a little bit upset by the way they treated the guy named alex in this discussion. He came out as really sweet, polite, well spoken, and they mostly dismissed his point of view without much thought. I do get where they're coming from about it. It's not about alex as much as it is the fact that anytime someone writes about sexism and feminism a guy will come over and says what he said - more or less nicely, and more or less honnestly.
It's a very grey area. I'm not sure there's an ideal way to deal with that. Probably more nicely at least.

The way we're talking about women and the female experience is a bit upsetting. It not only rejects in words at least the experience of male gay or straight who write and read fanfics, it also does that to gender queers, a point people like alchemia have often emphasized. I'm pretty sure Feminism is about being inclusive. It's about letting male play with female roles and occupations - since fanfics is seen as one, as well empowering women. But I understand its tricky to find the way to do it without getting back to the very sexist initial situation.

but personally I like the interaction and I value the difficult questions that it makes me ask myself about my interests
Yes! Defiitly! Difficult questions are always worth asking. Even without answers, questions matter so much!
