Honestly, this whole thing is just ugly. I read what he wrote. It was (mostly) ugly but contained a lot of truth.
Before you downvote/call me a Nazi, I'm a mixed race woman in tech.
I definitely see people hired just because of their minority status. I also see people hired who are minorities but also great at their job. It's not a binary pattern. But those who are hired just because they are a POC or female, yet are terrible at their job stand out. People notice it, but few say it.
Our company recently hired a black woman as a "Software Engineer" who can't write a SQL statement. She has a "taken some tutorials" level of programming skill as far as I have noticed and produces things very, very slow. People notice this, and it makes them angry. I'm sure the other engineers talk about this even more when I'm not in the room. Our boss is proud of how much he is "making the team diverse" yet it's only going to cause problems for the team.
I like to think I was hired based on my skillset, not to improve the numbers. I've worked hard to get here. People likely forget or don't care how "diverse" I am when I am working because I produce. And I fully support bringing in diverse candidates, it's essential to get those viewpoints, so long as they are a qualified candidate to start with.
I do think that men and women are biologically different and, it likely does contribute to a lack of interest in tech from women. Almost all of the women from my social circle are smart, pragmatic, driven and successful yet have zero interest in a technical career. They excel in their given industries but ours they want no part of. I don't believe intelligence is more prevalent in either gender, but I do believe there are some traits that shape who we are.
That's something that's rarely addressed, for fear of being ostracized.
As far as his "conservative white male" discrimination claims, I've seen that too. My boss specifically requested candidates that are not middle-aged white males. But it's nowhere near the same level of discrimination that people of color or women have endured for decades. Perhaps the reason people don't feel sorry for conservative white males is that if they are rejected by one company they can keep trying and will find an "old school" company that will hire them. We have not had that luxury, for blacks and women it was 100 nos for every 1 yes. It's not that way for white guys, sorry.
