I don't normally read this individual because I'm somewhat attached to what I like to think are minimum standards. But it seems abundantly clear that he's nothing more than a sad, self-entitled, egocentric little misogynist.
The physics thing, though, is just bullshit!
I have a STEM degree (engineering, not physics) and I'm literally a token woman in my job. I also line-manage a workforce of some 400 STEM professionals - almost all of them male.
The problem with women and STEM starts before we even enter a school for the first time. From the moment we're old enough to play with toys, girls are steered away from 'techy' games and towards socially geared play. Then, at school, we're assumes to be naturaally pre-inclined towards languages and social sciences. Our talents and achievements in technical subjects are all too easily overlooked. Once we get to pick our own subjects, the need to conform pushes us ever further into this corner - as does peer pressure. Who wants to be the sole girl in advanced maths when all our friends are in English Lit, after all? It's isolating!
University breaks all but the best and toughest of us. There's something almost indescribable about being one of only five women in an undergrad lecture of 300 students. When we drop out, this is as much of a factor as whether or not we're struggling academically. In fact, we don't struggle academically - we'd never have made it as far if there were the slightest doubts.
And then we go into industry, where we go on to be sexually harassed by our bosses and stared at in incredulity by our peers. Admin will develop an uncanny knack for putting us in the least technical roles available to someone with our profile. And, slowly but steadily, we'll turn into managers, administrators and book-keepers - at which point we start having kids and if everything else hasn't buried our STEM careers this one certainly will.
And then the few of us who survive somehow end up on all-female executive panels at industry events and get to publicly debate why STEM has a fucking woman problem.
In all fairness, we all know the answer: STEM has a woman problem because women and girls are systematically discouraged from making it in STEM. And - and here the viscious cycle begins - we won't resolve it until we do get more women.
Yes, this pisses me off. I'm also kind of an accidental expert.
