Look, I get it, people turn you down for jobs all the time. I am a white male, and I HATE looking for a job in my non-mainstream market, because I am constantly passed over for being a generalist/introvert/socially awkward/you-name-my-worst-social-traits-and-recruiters-and-hiring-staff-hate-it. When I get my foot in the actual door, my bosses always LOVE my work.

If I wasn't a, you know, a non-protected demographic, I could just hop on the internet and whine about how these strangers are discriminating against me for my [protected status] and that we need to fix years of bias, when it's really that they binned my resume for being too weird, too non-specialized, too X for their tastes.

The basic problem here is that there are too many confounders in why a particular individual is denied a particular position, and it's way too easy to cry "X-ism!" instead of actually breaking down the hiring process into actionable feedback for everyone.
