A huge thing that people overlook when they talk about past discriminations is that those discriminations came naturally from the long mists of time and human interaction and experience, right or wrong they were organic.
What is different about this modern discrimination is that it it is something gone into with eyes wide open, it is deliberate and self imposed by the whites onto whites, it is artificial, completely irrational, and destructive to any positive future for America , this came out of nowhere and is a repudiation of seeking a higher plain and attaining a new level of human awareness and interaction and the avoidance of engrained preconceptions, it is a reversal of advancement, and came from government and institutions and was suddenly and shockingly imposed against the people, it is not something that bubbled up from the people and found its way into the government and institutions that they created over history.
Your points are very valid. I agree with you.
