Look, sister, even if you were to prove to me that race was a social construct, I could still make a very compelling case for white nationalism. Cultural differences alone are enough to create conflict and irreconcilable differences. I could still fall back on Robert Putnam’s Bowling Alone which found that diversity erodes social trust. There’s a lot of angles use even with race realism.
After all, non-white racial nationalists usually don’t rely on race realism to justify their existence. Whites nationalists do as a matter of self-defense because we are blamed from the underperformance of other groups.
On the other hand, race being real would COMPLETELY annihilate your worldview. At very least, it would necessitate much more radical rethinking of it.
So if anyone is clinging here, it’s you. You need race to not be real a lot more than I need it to be real.
