I'm seeing a lot of people in here coming in saying "I mean I'm not racist" in 2020, where Blacks in America have all the legal rights Whites have, in fact they are virtually a protected class. It goes to show you just how far this brainwashing has gone. I'm in agreement with others when I believe thats it's actually communism dressed up as progressivism and anti-hate.
Its more that progressivism just combines excellently with Communism/Socialism because both would be essentially the dissolution of hierarchy and
asymmetrical power structures that oppress people.
When they try to fight against White Supremacy, this is their thinking, "Society has institutions that advantage Whites over non-Whites, and their continued existence props up an oppressive system of White Supremacy. In order to end White Supremacy we must dismantle the institutions that propagate and systematize the oppression of non-Whites to the advantage of Whites."
And when they talk about Policing as an institution of White Supremacy, what they are referring to mostly is the "disproportionate" incarceration and conviction of Black People in comparison to White People. Policing is of benefit to White People since they commit less crimes and there it is
to the disadvantage of Black People to have Police. So them getting rid of the police would be of advantage to Black People since they wouldn't be sent to jail at least as often as they are now.
Ergo, in supporting the Police you are supporting a system of White Supremacy and are their enemy. However, most sane people are left in the strange position where not wanting Black People to get gunned down in the fucking streets now makes them White Supremacists since that would require them to advocate for Police.
Disproportionate, Racial Bias, Black Oppression, all of it, its just euphemisms. What they want is to empower Black People against a hierarchy they perceive to be a great evil, any argument they use is just another way to advance that aim. It is pathologically cynical because their view of the world is so thoroughly tainted by an analysis of Power Dynamics.
TL;DR The commies are trying to subvert society by co-opting anti-racism as a cultural avenue to end hierarchy. All of it comes down to how hierarchies are inherently oppressive, thats it.
