the thing that gets me when some transmasc pipes up with 'not all men' or 'what about me?' whenever transfems and just feminists in general are talking about men is what I learned when I was first engaging with feminism. I was there in the mid 2010s when slogans like 'men are trash' were gaining popularity and actually listened to what feminists had to say about it. The thing they made abundantly clear was when they say 'men' they're talking about men who are violent, men who are complicit, the overwhelming majority of men who are misogynistic, systems of power, expectations. A point they made is that a) if you as a man feel called out by this you are one of the men being criticised cause b) if you were feminist enough you would have listened to them and understood the underlying logic and would have also stopped engaging and started opposing the behaviour they were criticising and c) feminism is meant to make men uncomfortable, patriarchy insists that women capitulate to men and consider their feelings, why does men's uncomfortableness matter more then women's rage at their oppression, why can't men handle being uncomfortable.
And this logic remains true with transfeminism. Whenever some transmasc pipes up it's a tell on themselves, why do you feel called out, if you were actually a transfeminist you'd already know the underlying logic of our criticism and wouldn't feel attacked, why do your feelings matter more then our rage at our oppression.
