Because to me personally this kinda feels like America is still stuck in those slavery/segregation times
Yes. American culture is very much based on social hierarchies, and slavery created a very easy, color-coded social hierarchy. So it’s hard to get rid of because a lot of people are invested in it - whether they admit it or not.
Americans (except for the most liberal) tend to look at race as a biological reality and regard anyone saying race isn’t science as woke extremism. Generally when science conflicts with common/traditional sense in America, common sense wins. The only reason quantum physics isn’t banned from schools yet is because probably only about 10% of Americans know the first thing about quantum physics.
Americans also regard a wide variety of racial discrimination - such as in dating (including who you allow your kids to date), or where you live, or where you send your kids to school, as “not racist”. This is considered not racist because the goal isn’t to harm racial minorities, but rather you’re just doing it to protect your place in the social hierarchy. The race-based social hierarchy. And if this harms minorities, well it’s not like it’s your fault right?
And if you dare try to suggest that the above is racist, people will get very angry at you and do things like elect Trump.
So yeah, racism is still very prevalent in the US.
Did rioting work for George Floyd? Every single police reform bill was killed when Fox News exploited the riots to portray the whole police reform movement as crazy.
Rioting just injures a couple of working class cops, gets yourself arrested, and plays into their hands. If you want the ruling oligarchs to fear you, don’t riot. Harm the economy. Boycott. General strike. Make the line go down.
