Framing

really I am just arguing against multiracialism and in favor of a eurocentric society, which is me arguing against current and common policy in the West which will irreparably alter our nations. You're ascribing positions to me. This diversity fetish is based on ideas of innate equality or the idea that humans are interchangable. Race Realism breaks this narrative and demonstrates that excessive multiracialism probably wont work out and that cant be fixed by 'trying extra hard'

with regards to race, I think race cannot be concealed so it will always be an impediment to any attempts at a unifying culture and that multiracialism carries inherent tensions if left to grow unchecked

and white nationalism was the de facto reality of the West during its ascent, and since departing from that in the 1960s we are seeing the failure of diverse societies.

And the way an ethnostate would be achieved is by repatriation, permitted auto-segregation, restricted immigration (not 0), and promoting the current demographic.

The perils of multiracialism are not necessarily diminished by IQ. And some high IQ groups still have their own societies, East Asia, away from us dummies.

Which is another objection. We are eradicating the diversity of societies

Race is a sort of nautral organizing principle for nations. IQ, as far as I know, isnt. Hasn't been demonstrated. It would be like "height nationalism"

why is it unethical and not welfare maximizing to recognize that diverse polities are worse than homogeneous ones?

Institutions arent separate from their populations. Officials cater to populations, come from them, and are raised in the context they create. They'll decide who takes the position, or the curriculum in the school where they are trained, or the political climate around the decisions they make.

huge risk to not care about demographics

my position is that genetics matter and inform material actions, which they do. It's a law of behavioral genetics. I have said as much.
