> I've never seen men, as a group, encounter the obstacles I've seen many female peers discuss
Though since we're on the topic - I can't speak for your specific anecdotes, but I'll say this: men may not face obstacles to the same extent of women, but they definitely face their own obstacles, and sexism against men even in this industry is a thing.
Affirmative action and hiring quotas are reverse discrimination. Being a women in this field gives you a leg up in terms of university admission to competitive CS programs and employment at competitive firms. Recruiters are often female and discriminate in favor of women. (I've experienced this numerous times firsthand). For your friends who were actually sexually harassed, the mere accusation alone is often enough to get co-workers fired and have their reputations ruined (see Adria Richards dongle joke).
So yes, females unfortunately face a huge set of obstacles, but they also face a huge set of advantages that shouldn't be overlooked. This victim mentality needs to stop at some point.
