I'm thinking you can only get this sort of weapon grade stupidity from homegrown idiots. Actual African immigrants are generally thrilled to be in America.
I think that the key to getting the Trump vote in the Black community up to 25%, is to flat out continue to pound away that Hillary has invited those who are harassing the Police for trying to maintain law & order in the inner city neighborhoods, into her political fold. There is a large element who would like to see more--not less--Police activity; whether or not they dare speak out in the present climate of hate that the Left has created.
