Why is there not a male nurse initiative? Or male elementary teacher initiative[1]?
I have to admit, I am strongly against things like "Girls who code". If there truly are issues in our culture that prevent girls from looking into coding, then absolutely let's get rid of those as best we can. But a girl can look into and explore coding just as easily as a boy can. There's really nothing stopping them. I have a few male nurse friends too. Nothing stopped them either, they simply found nursing interesting and pursued it. There might simply be fewer female coders because they tend to not be interested in this profession, same as male nurses.
