Two things I have noticed about American Black culture:
1. The lighter the skin of the 'Black' person, the more race obsessed they seem to be...Kaepernick, Obama, Shaun King. I'm not sure if real African people will even accept Kaepernick as being Black?
2. When American Black nationalists actually visit Africa, they usually calm down when they get back to America. Watch and see if his behavior does not change when he returns. It usually does.
I spent some time in Dakar Senegal. I could tell stories about Africa you wouldn't believe. The more Black Americans who actually go to Africa, a.k.a. 'the Motherland', and see what life is really like there, the better things will be for everyone.
