I'd like to think that there are no women rights, just human rights. But this type of mindset closes the eyes on existing problems and injustices, declaring them to not exist. It is usually a position taken from a position of privilege. You can think in terms of human issues because you are not subject to discrimination and reminded that the world perceives you as part of a group and not the individual that you are.
Therefore I stand up for women rights and try to help establish an environment in which we do no longer need to separate us into categories.
Btw, why are the nipples censored in the femen picture. It is not reflecting their ideas and I do not understand this fixation on female nipples, that do in fact look almost identical to male nipples.
