If you support mass immigration, there's absolutely no reason to tone down ethnic grievance-based sentiment because such policies will inevitably lead to White people being replaced by populations which see themselves as ethnic interest groups. This is the future of US democracy.
democrats legit need to ditch the anti-white racism, it's not quirky, it's not funny, it's not tongue-in-cheek, it's one of the major drivers of moderates/normies away from their camp
you can dislike that, you can think they're too thin skinned or whatever, but it is what it is.
