One is quite welcome to say "Asian" in the abstract. It's the part where one says that "Asian" is an socio-ethnic monoculture in practice that is uninformative.

At the very least, name the Asians you're talking about. India and China, for instance, seem to have a lot more representation among US programmers than other Asian nations.

Sure, but the same thing can be said about white people as well. Somehow, there is a disproportionate representation of slavic/eastern european people in top tier tech and fintech jobs, but it seems to fly under most people's radars when it comes to that kind of conerns. So we are back at ground zero with nothing useful coming out of this, now what?
