What IM2 is referencing is not "hypothesis and theories", it's science and the results of medical research. And that's "multiple degrees" not "a degree".
And when he rightly states that since you're not Black, you have never experienced the racism that was the law of this land for almost 200 years he is 100% correct. One of the benefits of being white in this country is that you never have to even have to think about Black people, let alone interact with any if you don't want to. Black people on the other hand, if we want to give ourselves the best chance to not just survive in a white society, but to thrive and achieve any goals we've set for ourselves, then we had to study white culture/society in order to lean how to navigate it, to exist in a world that at times could be very hostile to our very existence. And now people today, along with members of our Supreme Court are trying to take us back to the time when the United States was a lawfully segregated nation - not a century ago, but to the time just before the Civil Rights Act of 1964 was enacted.
Your open hostility to IM2 is very telling, that, along with the way you all allow your pet members to violate the Zone 1 rules with impunity but we get sanctioned for every little fact that we state that hurts the feelings of those members who espouse their racial belief in numerous ways.
So it's the fault of Black people that white racists have done everything that they possibly can, and are still doing everything they possibly can to keep the upper hand that they held for so long, by law, and doing all that they can to Black people to keep us from advancing, socially, economically, educationally and politically?
And most Black people have fallen victim at one point or another to the remaining vestiges of white supremacy upon which the United States was founded. It's unavoidable because in spite of the laws prohibiting it, racism still continues. That however does not equate to us being "willing" victims in the violations of others and for you to try to claim that we had some participation in what was done to our people and still to us, makes you no better than the original slavers and other white supremacists.
