@RichardMZhlubb, let me offer an example of what you must demonstrate in order to show systemic racism. It can be shown that the black poverty rate was in steep decline prior to Johnson's Great Society policy initiatives, legislation and programs, and after it virtually flatlined.
But this outcome, this effect is not evidence of systemic racism. Evidence must come from causes, from intent.
We might point to Johnson's saying "I’ll Have Those N*****s Voting Democratic for 200 Years" as racist intent but that's weak as argument. Johnson was likely racist, but his intent wasn't, he just wanted blacks voting Democratic.
Still, that should give you an idea of what your task is, to demonstrate racist causes.
