“There is a profound misunderstanding of what race really is,” Harvard anthropology professor Daniel Lieberman said at an event the night after the presidential debate. “Race is a scientifically indefensible concept with no biological basis as applied to humans.”

That alone is a killer to an Al Sharpton or Jesse Jackson let alone Black Lives Matters movement. 

Also most people are unaware that the term "African American" and  "African American community" is widely incorrectly used by many. The term “African-American” only appropriately applies to descendants of Africans brought to America as slaves. There are many, many people of dark skin color in American, some having African heritage but not all are descendants of those who were slaves.

It's way past time to start being a part of humanity and forget about using those childish crayons.
