We can do all the really important things, and if there are things we want to do that "society" thinks we can't or shouldn't...well then, all the better, because we'll prove we can.
Personally, I'd prefer not to have to constantly prove that I can do something "in spite of my gender". Maybe that's just me, but I'd like to not have to keep proving myself, over and over again, just because of my gender. I'd like to be able to just do something without having to fight for it.

Isn't that so much more of a victory than wasting time whining about it?
Well then, let's forget about fighting for equality so we can do anything we want - which, hey, who cares about little things like that? - and instead, um, prove that we can do anything we want... hey, wait.

Feminism is not whining.
