> There’s a lot of minorities that are well-, even over-represented - e.g. Asians, Russian immigrants, autists, people without formal education, … I’m guessing it’s one of the most welcoming and meritocratic industries!

How do you get to your conclusion from your statement? Simply having some minority groups overrepresented doesn't mean that the industry is welcoming. It may mean its welcoming to those groups.

And people w/o formal education isn't really a minority group. Any more than PhDs in computer science is a minority group that is overrepresented in the tech industry.

> But those aren’t the “right” minorities, and it’s not politically expedient to point them out.

This isn't about political expedience, but its about understanding the context of the discussion. Either you're new to the US or simply are ignorant to the issues of the post.
