Nope. Altruism promotes ethnic homogeneity.
Altruistic people promote stable societies with high life quality. This setup encourages mixing, and as a RESULT the population becomes more homogeneous.
Selfish people punch down which promotes others to punch down, which reinforces social "caste" boundaries.
I actually think this is also the phenomenon behind some white ruralites being more decent-than-you'd-expect towards individual POC.

You're correct, but the heart of this argument is really about dog whistling ethnic cleansing. They want a racially pure white society. That's it.
