I think the issue is a bit more complex than you're making it seem. Sure on a certain level it is a false dichotomy but you're really over emphasizing that aspect and falling into their trap. I think of it as the enlightenment fallacy - which is basically to exclude all forms of reasoning in favor of only logic or rationalism. Emotional reasoning is labelled irrationality - anything which is not logic can be safely discarded.

That is really the cornerstone of your argument. The premise is irrational, therefore has no power and there is no need to address it at all. All you're really doing is blinding yourself where your opponent does not. Your opponent is more than happy to make assertions over and over that affect us on a subconscious and emotional level. You mistakenly assume that the only way to counter these arguments is to stay logical, (a statement that requires belief) when that isn't the case at all. I'm not going to pretend to have the answers but it's unacceptable for people to carry this much shame and guilt about things they never did. This segues into other forms of control they have over us by lying about our past. The control is through the illusion of powerlessness.

I too, consider myself to lean left on social issues. The idea of promoting racial differences seems tough. But for some reason we respect it when, say Native Americans don't allow outsiders in, or we seem to get why Japanese culture can be so insular. But we simply do not ascribe the same value to our own culture. We are collectively ashamed of our heritage and it is a travesty. I guess the other issue is that it's a spiritual issue. All cultures venerate their ancestors and being prevented from doing that is really doing yourself a disservice. It terribly hypocritical to want to save the environment and preserve organic cultures etc and totally sell ourselves down the river. White culture has been hurt by religion, consumerism for so long that it's easy to think it doesn't matter anymore, it does matter, our roots connect us to a deeper part of who we are and we need that grounding to fight these elites. That's how I see it anyway.
