This is part of the problem with things like this - while good intentioned, it inevitably alienates another equally oppressed group.
Why can't we just have "Office Hours" and make it absolutely clear it's for anyone -- and actually follow through with the intent.
It just seems silly to says "these here are for only this one small group - and that's how we're going to help combat bigotry".
Combating bigotry is a worthy cause, but it is not the only worthy cause, and evaluating unrelated outreach programs by their impact on bigotry is a sort of rhetorical sleight of hand.
I think this is worth pointing out: there is probably no criticism anyone is going to have of this program that the YC partners have not already considered. It's 2015, and they're not dumb.
if a person is ill, you don't go around giving medicine to everybody so that the healthy wouldn't feel excluded.
I don't see this being much different than what being featured on Oprah's Book Club could do - sometimes things are overlooked, and using personal currency to bring attention to such things makes sense.
