You do realize that American blacks speak a southern American dialect of English and that these Spanish-speaking brown people are just as foreign and invasive to blacks as they are whites?
So the white minority thing is a misnomer.
But don’t let that impede the lefty W Post propaganda.
Because all black people talk the same.
Statements like yours show that you need to hang around people different than your face more often.
And black people do not have a specific dialect. I am from Philly and have a mid Atlantic dialect and accent. My paternal grandparents had a southern accent but that’s because they were actually from the south. However my aunt and uncles do not have one because they grew up in Philly.
My cousins grew up in Cali. They all have valley girl accents because they grew up in the valley.
No we do not all have the same dialect or accent.
