Most doms are men and most subs are women, which is a direct recreation of patriarchal power relations between men and women, with the men on top and the women in their place at the bottom as usual. Even if the number of doms/dommes was a 50-50 split between men and women, it wouldn't take away from the real life situation of women and what men do to us. That shouldn't be eroticised or treated as if it's a normal and acceptable way of behaving towards other people as long as it's dressed up as kink.
A female domme is not benefitting from it the way a man would, but she is still fetishising dominance and submission - something all women are forced to experience by men, without "consent" and without choice. Dominance and submission or rather subjection is the hierarchical structure that male power rests on, which is why men get off on it. The opposite of men in charge isn't women in charge, it's freedom for women.
