What percentage of "African Americans" are the conservative leaders you are talking about? A very small percentage. Yeah in general in many parts of amerikkka you will have a somewhat "higher" living standard than in many parts of africa. This would apply to you as much as to a slave descendant.... don't you live in amerikkka?
Most Black people in amerikkka live in the worst conditions that amerikkka has to offer. A huge amount of us are in prison getting our heads slammed into walls by guards, getting raped up the buttocks, etc. etc. Where my auntie stays in Bed-Stuy there is no hospital nearby if she or her kids were to require emergency attention. The difference between the teenage and pre-teen "gangbangers" who I've met in amerikkka, and the child soldiers of Sierra Leone or Congo, is only one of degree, and they're not that many degrees apart.
I fail to see how the MAJORITY of African slave descendants in amerikkka have benefitted from anything to do with amerikkka. On the contrary amerikkka has benefitted from them and spat in their face.
The negative attitudes towards continental Africans that you point out... yes that is true. It's due to miseducation and media brainwashing. People just don't know any better. Also, it works both ways, and you know that's a fact.
