Why is there a so called African American Culture, when there is no A.A. Flag. Like the Jews & Arabs?

maybe it's because "african american(or black)" is a race/nationality while "jew" and "arab" are religious groups. and if blacks had a flag, hispanics and asians would probably want one too. also- african americans, just like other races/ nationalities/ ethnic groups have ancestors who may be caucasian, asian, hispanic, native american, etc.
