How can a situation where a child enters a classroom full of enthusiasm and leaves a year (term?) later depressed not be an "actual issue"?
I am saying that it IS an issue, but that the issue is not one of gender discrimination, just one of kids, and humans, being dicks - and you can't combat it purely on gender lines as all you're doing is treating a symptom rather than the disease.
Btw, you need to get away from the habit of directly attacking the author and focus instead on attacking the argument.
You're right that by abstracting things away you can just create a philosophical point with no path to resolution, but you can also actively inflict harm by tackling an issue in isolation without evaluating and understanding the root cause.
This is the same philosophy (general problem, specific problem within that general problem that we think we can act on, so act, without looking at the general problem) that lead to rampant mercury poisoning and insanity across the globe in the late 19th c., as a poultice of mercury nicely clears up the sores from syphilis - but does not cure syphilis.
Wrong. You're assuming that all forms of bullying are equally bad. This is patently false. Bullying based on traits that already set you apart can reenforce imposter syndrome. Specifically in the case of programming, a woman in a male-only class will already feel isolated and like she doesn't belong. Being bullied with gender-specific insults is much more harmful to this persons potential as a programmer than being bullied with gender neutral ones. So addressing specifically the sex-based bullying is necessary in addition to bullying in general.
It's not about gender. It's about ostracism. You don't have to be female to be ostracised. You just have to have something, anything, that sets you apart from the crowd.
This is the societal control mechanism we have culturally evolved to ensure conformity and "strength" in groups. It is really, really, really fucking dangerous, and leads to fun shit like Nazism. It's also really powerful, and is the basis of nation states.
Ergo, the problem needs treating at its cause, which is a cultural illness, and is far from simple to treat. You cannot simply resolve one emergent aspect of it and then expect to treat each aspect the same way. You do not cut down a tree by plucking at its leaves.
This is certainly true. What I meant to convey was that in the context of a programming class, being bullied for a trait that is itself already suspect within oneself reenforces it and thus is more damaging. If that girl had been bullied in the programming class because she was fat, it may not have had as much of an impact on her decision to pursue the career. Being bullied because she's a girl on the other hand, had the secondary effect of reenforcing the idea that she doesn't belong in tech.
We as a species have a remarkable proclivity to be very unkind.
The way to deal with it is "Suck it up." i.e. have self-confidence and act you, yourself, personally, better than others. Lead by example, not legislation.
