I grew up in Idaho, I was a grown ass adult when I learned about it, stumbled into it really.

I found out about it because of the black history museum in Washington DC. I knew about some of the events that happened, but had a make eye opening experience going through that museum (And the Native American museum).

My highschool history classes 1000% glossed over 20th century racism and oppression. It was like "the civil war happened, then the civil rights movement made everything hunky dory, the end".

I stupidly thought racism was just something in our distant past. Antiquated ideas no longer here. I was a naive idiot.
