Ok... So there's quite a bit to unpack here. First; the website, as has been point out, is just a site to get you triggered, which you have a uniquely uncanny ability to find those types of websites of late.
Second; she's a professor at a Liberal Arts school most of us had no clue existed.
And B; she's not really wrong. Although she's pretty inflammatory with her own phrasing. I'm pretty sure everyone knows STEM has been a male dominated field, and there has been a huge push to get girls and women more involved the last 20 years. Also, from probably the 1400's to the end of the 20th century the history of physics and science was dominated by white males (if you only look at the western history, which is what's taught in higher education here). Marie Curie, Neil deGrasse Tyson, and Michio Kaku (bet you actually had to look him up, even though you probably know his face and voice) are pretty rare when you have Galileo, Newton, Copernicus, Pascal, Kelvin, Plank, Hertz, Ohm, Bhor, Tesla, Einstein, Oppenheimer Heisenberg, Schrodinger, Hawking, etc. Those are just the ones I remember from the constants we learned in school and random history. I mean Google "well know physicists" and the only none white male that shows up Marie.
Physics may not be inherently racist or sexist but it is most definitely dominated by the white male. To say otherwise just foolish.
