That's the issue with first-world "social-justice warriors", like the author of the linked opinion piece. If you disagree with their premises on factual grounds, you're labeled as part of the problem. It makes honest discussion impossible.
For example, you completely ignored the point that PG made. You didn't even attempt to address it. You just labeled him as the enemy and went on to make your own point.
He made a good point, but in my mind, he didn't go far enough. Both (American) mathematics and SV are disproportionately dominated by east-Asians and Indians relative to their respective population sizes. Why does everyone ignore this?
