Black leftists are very aware of this and they're aware of how capitalism and racism work hand in glove.
America literally would not exist without capitalism. Capitalism as we recognize it today was what allowed Europeans to travel by ship to north america and other parts of the world. By building companies(like the British east India company) they could offer shares to investors for a price. That money would finance the construction of the ships, crew, weapons, and other supplies.
Once those expeditions inevitably returned with valuable resources, the shareholders would gain a piece of the profits from the sale of those resources. Black people weren't enslaved because white people hated us, we were enslaved on a mass scale because we were considered livestock. Telling a white man he couldn't have a slave was like telling a farmer he couldn't have a plow or cows.
The racism was a tool of imperialism which itself is motivated by the bottomless greed of the wealthy. By convincing "lesser" people that their only path to acceptance is either becoming servants for white people or being white themselves, they will eventually adopt self-hate and seek to rise through a racial caste system. The Italians and Irish Americans are some of the most anti-black people in america because they were initially told that they are not truly white. To gain acceptance and access to the blood soaked riches of white supremacists, they tried to build solidarity by hating black people even MORE aggressively than the average white of English, French, or German descent. Jews are also extremely anti black for this reason too. Isabel Wilkerson wrote one of the best books breaking this down(Caste).
What you see with Latino anti blackness is just another chapter in America's story of hatred and anti black supremacy facilitated and enforced by its wealthiest citizens. In a racial society, competition for resources motivates hatred of other races because if the belief is if others are eliminated from the competition, THEY will have a better chance of success. It has worked exactly as planned for literally hundreds of years at this point. Reprogramming will take hundreds of years more, and the elimination of the financial incentives that come with anti black racism.
