"Considering that individuals get their viewpoints from their local culture" wanna expand on that since you have stated elsewhere that there is no defining cultural differences between groups and races here in the US :) thanx, bill
What I've said before is that there is no "black culture" in the US.
That being, the blacks in Seattle do not share the same sub-culture as the blacks in Alabama which do not share the same sub-culture as the blacks in New Orleans.
Each of those groups has more in common with the culture of the USofA than they have with each other.
