The past 80 years include not just Vietnam but also the most significant legislative period of the Civil Rights movement. I'm not even that old but my dad was born before legal segregation was ended.

Right. If people think BLM is controversial, check out the Black Panthers. BLM just wants a kinder gentler capitalism, the Black Panthers wanted to overthrow the shit and establish the dictatorship of the proletariat.
