Honestly, other than the historic genuine anti-blackness in Latin America (due to the colonial history) IMO the west has just really done a good job of cultivating inter-racial community grievances. For instance the (now genuinely felt rather than just ignorant) "anti-blackness in the Asian diaspora community" is well known in the west, but the reverse is also absolutely true- and there's all sorts of other grievances each group can have with the other, etc. All capital needs to do is declare open season on one group or another (hate crimes and crimes against Asians for instance), play favorites and hypocrites, spew their usual narratives, prop up their favorite self-hating or other-hating POC talking heads, and provide conflicting incentives (like affirmative action despite its flaws, and on the other hand genuine and undeniable extreme racial discrimination against Asians) and while solidarity is not all lost, things get toxic as all hell.

I've had a lot of great, actual solidarity in the west, sure. But the truth is also that for the broader society I don't have much hope for racial relations (re: whites and minorities, or minorities and other minorities) getting truly and properly dealt with until the system of empire and white supremacy is stomped to the curb. Having seen how things could be like elsewhere (not to claim that Singapore as an example is perfect or even based, very far from it)- it's incredible the difference in how things are, when a society actually tries to integrate its people together into a harmonious yet undeniably diverse society- couldn't recognize it for what it was and appreciate it when I first saw it, but nowadays- well, the difference could not be clearer, flawed as it may be.
