That edit is fine and says a reasonable thing that I agree with, but there are two reasons why I said "women" instead of "gender".

1. "Hackers don't give a fuck about women" is a more shocking statement than "Hackers don't give a fuck about gender" given millennial social justice sensibilities. That shock was intended, because it demonstrates to readers who aren't hackers the difference between their view and the hacker view, in a very visceral way. When you read, "Hackers don't give a fuck about gender", you have to think about it to realize how fundamental a difference in thinking that is. But when you say, "Hackers don't give a fuck about women", you can feel how different it is.

2. Gender is also a much larger issue than women in STEM. In the context of this discussion, "Hackers don't give a fuck about gender" is true, but in a larger context, I think hackers do care about gender, because gender is very hackable.
