I don't know how old you are, nor how you were brought up, but there was a time, when I was growing up, when true "color blindness" was alive and well in some places and social strata, here. There was absolutely NO "US VERSES THEM" crap; none at all.
OTOH...yes, there was a color strata ( still is, though not necessarily the same way ) amongst blacks.
And you're still on the wrong end of everything, with your idea re "eventually all races change" garbage.
People are people/HUMANS, no matter what race they are! Some are intelligent, some aren't, some are nice, others certainly aren't,and it has ALWAYS been this way, no matter how far back you want to go!
I still see a lot of tribalism out there. Whites have deemed it quite unacceptable among themselves and it should be that way. Tribalism is stronger among minorities and you could argue that white oppression or other pressures makes this acceptable. I would like to see an end to it completely but I think there’s a long way to go particularly if there’s too many people in denial of it.
