The obvious reason is that we live in a sexist world. if women were treated the same way as men your comment would be true.
Pretty brilliant logic, there. You missed OP's point entirely.
I interpreted it as "The reason women want to be treated differently [from how they are NOW] is that the world is a sexist place." Not, "The reason women want to be treated differently [from MEN] is that the world is a sexist place."
Even those who advocate for affirmative action generally do not deny this. You are behind the times.
"some guys don't know how to act around women", it was said. Well, people should know how to act around people, no matter gender or race. This statement does not collaborate to end with any kind of discrimination: it is already discriminating.
