There's a bunch of needlessly inflammatory bullshit in that article. "Innumerate woke Bolshevik" and making fun of someone because he thinks she looks like a Harry Potter character. This guy seems like nothing more than a high school bully. E-mailing someone asking them to respond is nothing more than a fig leaf.
Huh? The linked article is nothing more than "this guy is black, so therefore helping any underprivileged black people gain university admissions is bad"
It's outrageous racism. A conclusion about all minorities based on one person's math mistake, where the logic is entirely based on shared skin color.
If you replace the races and make it a conclusion about legacy admissions or something, it's obviously stupid and illogical, right?
"This white guy doesn't know Afghanistan from Kazakhstan. More proof legacy admissions is bad!"
