the second part wasn't about what you said, but an example of how the claim "if a person gives up something, then they weren't passionate enough" is nonsense.
to give you a better example: since guido van rossum gave up leadership of python, does that mean that he wasn't passionate enough about it?
absolutely not. but how he was treated destroyed his passion, and he couldn't handle it any more and burned out. this is the argument above. women leave despite their passion they got more pain than they could handle. just like guido.
How did it destroy his passion? Did he quit all of CS entirely, including coding as a hobby, and took up shit like fishing instead? No? Then it didn't destroy his passion. He quit Python but Python isn't his passion. It's just a manifestation of it.
If you really love knitting then you're not gonna quit it altogether because you once had a shitty experience with a knitting group. You're just gonna find another knitting group or do it alone. But if you do quit, then you never were passionate about it. That's my point and that has nothing to do with female gamers or whatever juvenile bullshit GGP is currently interpreting into it.
And that second part of your post is really damn far fetched. I never even mentioned anything remotely related to gender.
