The reason that there is not many black grandmasters is because in African countries there isn't a strong tradition of chess compared to European countries. I think the OP was referring to black people in the USA, and it is the same: there just isn't a strong chess tradition in African-American communities. Likewise, there isn't a strong basketball tradition in Eastern Europe, India and Russia. There is no racism, it is just tradition.
Chess is Inherently Racist Chess.com has to help solve

No racism rule: THERE ARE NO TURNS.
But then that would be like saying that white and black are both bad colours. Which would be like saying animals of different colours are better than humans! And we all know the best animal factually is frog 🐸.
Now I think we should create an animated chess board with animated humans and animated frogs, letting the frogs go first. See, no more racism now!
Frog to d4
Frog Should Move to E4 or Nf3

Although Israel does have a disproportionately high amount of GMs
Children whose parents have a personal job hear an average of 2,100 words per hour. Children whose parents have a working-class job hear an average of 1,200 words per hour. Children from families on welfare (unfortunately most black people) hear an average of 600 words per hour.
If you disagree with me, you’re disagreeing with Thomas Sowell. This is all almost a direct quotation from him.
And what caused this to be the case? That's what needs answering.
Racism in the 1900s I'd assume
There was no "racism" in the 1900's. There was only classism.

I pointed all that out but I'm afraid it IS racist and deeply offensive imo. It even offends me. Patronising black people by saying they needs a knight odds is extremely insulting!
It can't be a racist joke if the OP doesn't believe it himself.

Israel has never produced a World Champion.

Lowest class people are slaves, a word derived from slavs because slavs we're so commonly made slaves.

What you are saying is actually a commonly held misconception. The word "slave" was used far before the 1800's, so you're wrong.
I said classism, not classicism.

One way racism is the scourge of modern woke society. The belief that racism can only be white against black and not black against white.
It creates institutionalized racism. It awards entrance into universities of less qualified people due to skin color. It keeps out top students if they are a certain race. Really it is disgusting to see and is the ultimate hypocrisy.
Ever heard of the ‘separate but equal’ laws?
Segregation wasn't about racism from the working class, it was racism inherent to corrupt system that had infiltrated America and the people behind it were not Americans!

The institutionalised racism against Asian people that is going on today comes from the racist BLM and Antifa supporters.
