I think for a lot of POC that live in a predominately white neighborhood and go to predominately white schools it's a rude awakening. For a lot of blacks in mixed environments too. I know it was for me living in "White Folks City, USA. I graduated college in 2000... but way before that I knew what your Dad said is the truth. My mom basically related similiar sentiments to me all through my teen years...and even my father was clear about my brother and I understanding those things. Not sure why my younger brother got it way faster than I did.
I think for me personally growing up mostly around white people..it took me longer to recognize the full truth of what "our parents" were trying to convey. The funny thing is looking back.. I saw all sorts of evidence to prove their point very early on. I think I just didn't want to believe it but deep inside.. I knew. Because what else can you make of.. "well you're not like them
.. you are "different" everytime a racist conversation came up about black folks. And some of the answers I got when I got bold enough to ask.. "Not like them in what way ..how am I different ?" Would make your hair stand on end.
This kind of ish will PUT a chip on your shoulder if it wasn't there before that's for sure..but if you don't control it then you are giving in to your uncivilized animal side..so there ya go.
