Um, just delurking here to say that I, and many, many women have been alerted to feminism purely through reading these boards.
Not only are they informative and educational, it is precisely this kind of interjection by (some) men, which solidifies opinion.
There are lots of men who post on these boards, who are brilliant. They get it because they are both invested in women's rights and informed. That is the key word - informed.
Many women like me are NOT educated about the basic tenets of feminism. But, as we ARE women, what we read on here just resonates - I recognise it. The lived experience of being a woman, if you question it, cannot fail to lead to feminism.
It's women's lived experience that leads to them educating themselves about feminism. As men don't, and can't, have that, they have to learn first and then accept it on faith.
It might not feel to them as though they are derailing or trolling but to the women who can predict it almost from the first sentence, it's obvious and follows a highly predictable pattern.
