We probably wouldn't have even minded or noticed it if the people who replaced us continued the same egalitarian tradition we had. I think for many of us the destruction of that is much more upsetting than everything else (or at least that's what triggers the reaction.)

Yes, that's been a blackpill for me. When you look at these institutions today you see what looks like assimilation, but it's superficial. For example, you might see WASPs and non-WASPs at Harvard aligned in support of social programs. But the former are motivated by self-sacrifice at the expense of their own group, while the latter often are motivated by self-interest in favor of their own group. Similarly, for the former, any sort of ethnic identity or in-group preference is condemned while for the latter those attitudes often are promoted or encouraged. At Harvard, it is not taboo for anyone to say "my ancestors built this country”—except for those whom that statement is the most true.
