I think a lot of men who scream loudly about being feminists are just power hungry, career obsessed opportunist, who will jump on any bandwagon that will strengthen their position. They don't care about women, sex workers, trans or whatever comes next, they only care about themselves. If in 5 years there's a new group or cause that's at odds with trans rights, but is growing in popularity and one could build political capital supporting it, they will abandon TWAW without batting an eyelid.
