This thread has descended into a compendium of personal experiences and conspiracy theories.
What I know now: everything is male dominated, tokenism is alive and well, and ethics are (apparently) situational.
So how exactly is STEM failing girls, again? I'm still waiting for that missing link that proves the agenda to keep girls (from an early age) from entering into STEM educations and thereby, careers. There is, as of yet, no convincing evidence that this phenomena is anything out of the ordinary. Surely, we'd have to analyze every known profession for gender disparity, to have a comprehensive discussion regarding gender demographics in the workplace. And we'd have to, conversely, analyze which professions are female dominated, and why. Then, we'd have to launch initiatives to bring more men into the fold, where they currently are lacking.
On personal experiences, here are a couple of my own. I had an abstract algebra professor who was a woman, and one of the most amazing mathematicians that I've ever seen. Her teaching methods were second to none. I had a proofs and problem solving professor who was a PhD in mathematics, and insanely brilliant. I wonder if anybody told them that there were forces at work keeping them out of this field. Or the countless engineers, scientists, and mathematicians that I worked with at NASA, Boeing, etc, who were also female. (and more than capable, might I add)
I've tried to be objective, but this topic has no teeth. I see no reason to believe that women/girls have any less chance of entering STEM careers/educations than men/boys. Sure, there are cases of sexism and gender bias. But that doesn't mean that it's endemic, or that the Illuminati are keeping the woman down.
