Racial Solidarity? Get the fuck out of here with you're fucking Leftist garbage. Europeans have never had "racial solidarity". Even when White Supremacism was actually a thing, "lesser whites" were still being discriminated against including poles, ukranians, russians, croats, etc. Hell, there was a massive anti-German discrimination in the US. White Supremacism basically never existed outside of the Anglosphere colonies. It never happened in Europe. How have you deceived yourself so thoroughly.

And then, of course, we already know what "racial interests" actually mean. You don't give a shit about white people. You're not interested in improving anyone's condition but your own. You'll stand there and preach "racial solidarity" while putting a white guy up against a wall and putting a bullet in his head for not adequately supporting you, should you ever have the power to do so. Feminists don't support women, Labor organizations don't support workers, Racialists don't support members of their race. You're just standing on the necks of people stupid enough to believe you so you can be the highest crab in the bucket.
