To preface this: I am white.
To any white people who are even slightly upset about anti-white sentiment, ironic or unironic: you need to get the FUCK over yourself. Read The Wretched of the Earth, Open Veins of Latin America, How Europe Underdeveloped Africa, Divided World Divided Class, White Malice, Late Victorian Holocausts, Unequal Exchange, Neo-Colonialism, The Wages of Whiteness, and a thousand other books until it fucking sinks in.
Every "white" country on Earth (barring maybe a few of the most backward European states) is parasitic. All siphon wealth from the non-white world into the white world, both externally and internally. They then distribute this money, to a very large extent, on the basis of race.
This means that race is a factor in class. That's why the most useless and anti-revolutionary tendencies of Communism all come out of Europe. You can see this fracture play out in every "white" nation. Even the "radical" white population breaks solidarity with the colonial population. White labor unions rejecting PoC, white Communist parties failing to grasp the race question and behaving chauvinistically, white "radicals" turning against anti-colonial fighters.
In light of this history, this class dynamic, and the ongoing racial depravity, to chide PoCs for "undermining solidarity" is the height of arrogance and chauvinism. Get the fuck over yourself. Unless you want to hand over the 90% of your material comfort that you owe to the accident of your place of birth and skin color, shut the fuck up.
