What you’re effectively saying is, “We’re specifically not focused on equality, only on where women have it worse than men.” And that’s fine, but then don’t also say, “If you support equality you support feminism,” because both of those things can’t be true at the same time. “We want to achieve equality between the sexes and for the most part women are disadvantaged, so we will focus on the inequality that is impacting women until they are at least on the same level where inequality is impacting men,” would be more appropriate in my opinion, but certainly isn’t going to be a winning slogan.
