Chomsky was not prepared to cede any points either. In many places, he does not respond to the probing questions asked of him at all (this is assuming the poster didn't add them in afterwards) instead opting to insult the poster.
Poster:
1: By what mechanism do white supremacist elements impose American black culture on the American black community today?
2: For example, how is white supremacy responsible for single-parent families in the American black community? Allegedly single-parent rates have skyrocketed since the Civil Rights Movement.
Chomsky: Racism is quite extreme today, and by many measures increasing. I don’t know what cocoon you live in.
Perhaps you are completely unfamiliar with racism and its impact, in particular, the extreme racism experienced constantly by African-Americans. If so, I would suggest that you learn something about the world, and then you will understand the mechanisms very well. If you don’t want to have direct experience – which is not that hard –then at least look at the literature.
Again, try following your own logic. It’s not genes, so it is circumstances. Do you perceive any circumstances beyond the extreme white racism that it takes real effort to be oblivious to?
> He even hints at OP's "intentional ignorance" many times too.Hinting at ignorance is not helpful unless you show a path away from ignorance. Saying that something is obvious or trivial (as Mathematicians say) is not helpful. If it is truly obvious, just provide evidence.
Now this is not to criticize Chomsky, he is still replying rather than remaining silent. And with his limited time, it doesn't necessarily make sense for him to give a solid argument in that case, but his argument in that link wasn't convincing.
