@froge yeah and it's not only that, it's also invalidating and erasing the experiences of men who do suffer from heterosexism and cissexism, like gay men, trans men, gendernonconforming men.
I have had several gay/trans men friends who had to distance themselves from feminism for selfcare reasons and that's just fucking sad and makes no sense, because we may not be marginalized in exactly the same way (but who is anyway?) but we are all not on top of the food chain in patriarchy and we could be fighting it together.
