What are the figures for Millennials and Gen Z?

I don't disagree with most of what you said, but I think race mixing is low on the list of issues we face. The women with shitlib beliefs are a problem, but many of these women are married to white men (also shitlibs) and have white children.

There are definitely mixed-race people like you describe, and it's a problem. I do wonder it's cultural as it's something that's become prominent in the last 15 years with the rise of overt anti-white politics and wokeness. I grew up around mixed people in the 1990s and I don't remember any of them having a chip on their shoulder about whites or "racism".. actually the mulattos tended to resent their absent black fathers. The only one who grew up to be a piece of shit (drug dealing/gangster) was the one who still had his father (also a piece of shit) in his life. He has BLM shit all over his social media. I don't know as much about Hapas as I've rarely encountered them.
