still a minority
I increasingly find I notice with the men in my own family, all decent, nice humans, men can rarely be buggered to care about anything that doesn't affect them. Which includes all women's issues and women's experiences, my df has said quite frankly 'well it doesn't bother me, does it?'. It's part of the privilege of being born male in our culture. Females do the job of managing everybody's needs: it's the burden that comes with being born female. They've even tried to rebrand feminism as 'sorting out equality for everyone'.
Where males get interested is where their own interests get affected. My df commented about how all this trans politics didn't affect him so why care, and then I explained what his granddaughters will deal with in their changing room and loo, and what his daughters will experience, and he went apopletic and wrote to his MP. Because His Property then stepped on by other males.
I do honestly think this is why some males support the TRA line: because they get the concept of males wanting x or y, because males. Part of their team. Females on the other hand? Female problem, and females are everyone's mum anyway, and there's the whole enjoying competition thing and that it's quite nice to be on the winning team and see how men are more powerful and get what they want against women.
Equality, for men, is largely about considering other men. This is tragic, if you're female its absolutely fucking horrendous, but it is true. This is what we're fighting.
