I've already addressed the use of the word sexist, so I won't bother to repeat myself on that score. Asking me why we "penalize" all men and why we even need an all-female group, along with continuing to insist it's sexist - are you seriously telling me you can't see how that is an attempt to shift the burden of proof onto us? Such negative phrasing clearly indicates to me that while you're trying to be cool under your cover of "good idea", it's the but in the statement that reveals where you're really coming from. If it's a cool idea, it's a cool idea, period. No "but" needed.
