My daughter graduated form high-school last year. Not only had I not heard a single case of girls being refused entry to anything - most of the times it seemed like my daughter and her female friends (most of them straight "A" students in a very competitive high-school in the Boston, MA area) were almost harassed to join the math club, the robotics club, etc.

None of them had any interest - they all found it "boring". The reasons are complex and a another topic, but in short, part of it is biology, part of it pop-culture where "nerd"/"geek" is not something you want to be.

I was questioning the statement "many examples of girls being actively refused...", because the poster provided an example of ONE incident. I provided valid observations from my own experience, providing contrary evidence, just to make a point that we cannot form an opinion based on one event.

It's not. I can see how this myth took root on HN, but it's funny how persistent it is given that it was clarified quite a few times even by PG.

They probably went with robotics over something like French history because the program can only work if it is interesting enough to get kids to sign up.

This is a dumb example.
