It’s subtle but right there in the definition;
the advocacy of women’s rights on the ground of the equality of the sexes.
Did you catch it?
It’s not “Equal rights for men and women” but “women’s rights”, the rest is subjective. There’s no call for women to have the same rights as men or visa versa, but the acquisition of rights in order to feel like they women aren’t put down.
This is why the fact that women not only have all men’s legal rights, but have more rights than men, doesn’t bother them in the slightest.
It’s rare to to find a feminist who advocates for men’s rights because as soon as they realise what feminism really is, they stop being a feminist.
