Predicated on what? What's your proof that such prejudices exist, or that they're applied more so to women than men? Furthermore, what's your proof that discrimination is the form of social activism required to fix this unproved prejudice?
In any debate around this issue there seems to be a lot of working backwards from the evidence to whatever theory the commenter personally supports. People who want to believe that prejudice and sexism 'keep women down' cite the fact that men are predominant in tech. People who want to believe that men are more predisposed to enter tech than women cite the exact same evidence. This isn't how logic works. Unfortunately for the latter group, it's not possible to prove a negative (i.e. the absence of sexism), so the former group will actually have to present evidence showing that prejudice is the best explanation for the gender gap in tech.
>Who are these women being given more than a fair chance?
Ignoring the facile pretense that every tech event is somehow exclusive to men simply because more men choose to attend, I'd start off by saying that this event -- this event which is enforced as exclusively women-only -- is evidence of women being given gender-based advantages. It requires Orwellian levels of double-think to look at a female-only event and pretend such a thing isn't sexist, while at the same time decrying the sexism in tech from the mere unexplained fact that tech contains more men than women. But this event is too hot an issue for both sides for either party to concede that it's proof or disproof of a female advantage in tech.
Instead, I'd ask what you think constitutes fair, and what constitutes equality? It seems that the answer to this question is what really divides the two sides in this debate. I -- and I assume most who think events like this are destructive -- would answer that fairness and equality relate to negative freedom: the freedom from someone restraining you from pursuing your goals i.e. we would all be more equal if the only thing which stood between us and our goals were our own skill (or lack thereof). If you disagree with this goal, could explain why? And if you do not disagree with this goal, could you explain how you justify discriminatory events? (And if you could do so without sarcasm, that'd be fantastic, thanks.)
