I don't agree with mreiland about not sticking up, but I also want to point out something important that I get the impression that many feminists miss: That men in general have more power than women in general does not mean that all men have power, or that even most of them are in a position of power.
This is true, but in a male dominated environment, there are usually men who have more power than women and if they don't use at least some of their power to support the cause of equality, they are supporting the status quo.
