Juells, no bonafide woman I'm afraid, two kids cut out of me and everything 
I find that slightly disingenuous, Rat since I've seen you argue on other threads that because you have no issue with a certain situation (unisex toilets, mixed sleeping accommodation on trains, mixed sports) no other woman should have an issue.
My position fermat is not to argue a point because I'm okay with it, but because I believe it is the right thing - for women, for people, I believe it is right. I will argue the toss on that (although I've never talked about trains), and I will be right or wrong, I will change my mind or not. I talk about sport as a sportswoman first and foremost - I've always said that - but unisex office toilets, as a feminist i think that is right. Same with pronouns - I'm against rigidly biological use of pronouns as a feminist, I think they are bad for women and they do not serve women, it's not about how I feel about them.
So yes, ideally we should be doing away with stigma around periods, that would be lovely. But at the same time we are playing this game in a society where body-shaming of women is all pervasive, where male sexual violence is endemic, where men do perve on women in spaces like toilets given half the chance.
I agree with you, and that's why there is a discussion to be had and why we should talk it out as feminists and come to our conclusions based on that discussion. Perhaps some of us (me included) are slanted too far one way and some of us too far the other - but it should be discussed.
