I have a hard time following this line of reasoning. I don't think GP's point is to "ignore systemic discrimination". Rather, it is to ignore those things on which people are discriminated. How can you discriminate against, say, race, if you don't pay attention to the person's race?
Specifically, for tech, if you happen upon a code written by someone called "didgetmaster" on github, and the author makes no comment about who they are as a person, how does this contribute to discrimination? Isn't this the whole point of anonymous resumes and such to fight discrimination against minorities for employment?
The issue arises when people disagree on what reality is.
When most Americans are running on pure ideology and a (quite unearned imho) sense of moral certainty and superiority, they assume their worldview is the objectively correct one, and everyone who disagrees with them is "a bigot."
Both sides of our divide have some psychotic people who do things like murdering people. But absent actually harmful acts like that, disagreeing with you doesn't make someone intolerant. It could be that your framing is wrong, or that there isn't one black-and-white objective universal right way of framing an issue.
