Perhaps Github is merely a business doing as they see fit?
(Note that this is merely a reply to your comment in a vacuum, and shouldn't be construed as me supporting either "side" in this thread.)
Ex: You should have the legal right to believe that all green-skinned humans are inferior to blue-skinned humans. But that belief makes you a jerk and I will judge you for it.
But we should confuse how you or I feel with the aggregate behaviour of HN in toto. My observation is that as a herd, HN approves of the legality, morality, and sanity of businesses, especially tech startups, making unconstrained choices that may appear "discriminatory" to others.
Mennään saunat, miehet!
2. I meant neither Nazis nor Hitler. I merely pointed out that if they were giving free accounts to a group that is not (considered to be) discriminated then suddenly it wouldn't be so cool.
And just in case: there are many white males with blond hair around, I know quite a few personally and I've never suspected them to be Nazis. If you have any proof that some of them are give me a shout so that I can unfriend them!
What I'm sayin is that justifications like this one:
"This reluctance has good reasons behind it: fear of being told they are bad programmers, fear of being publicly mocked or harassed, and even fear of losing job opportunities. All of these are greater risks for women on average than men."
are IMO simply not cool. You discriminate one group of people, favor another group and all that in the name of equality.
Also, does a transwoman count?
