Here's the thing (prepare for potential sperg-out, but you asked)

Dysgenics runs deeper than racial differences. It hits *all* races. So while denial of differences might reinforce the machine of dysgenics, it isn't the machine itself

The machine itself seems to be "liberation;" a skewed ratio of urbanites to ruralites; the cargo-cult of education; and probably mass migration too (more important than that they tend to be lower-IQ is that it almost certainly depresses native fertility too)

In other words, the ideology that seized complete power after WW2, what you could call neoliberalism (or globalism, or simply "liberal democracy")

Which, in practice, is now the elites using the lumpenproles to wage genetic war on the kulaks
