Agree. I lived in Georgia and the time was late 40s and early to mid 50s.And you're how old? You pretty obviously grew up in southern Democrat strongholds. I've never seen anything of the kind. I've read about it but only where Democrats held very strong majorities. Blacks didn't learn it from any "us" of which I was a part.
We usually remember best and most vivid memories from childhood as we age.
As an adult I held an authority position in my community and later. In my state as a criminal justice official.
