I definitely agree with the basis for this: slavery never ended, it simply changed from pure chattel to "slavery with extra steps."
However, when it comes to BLM, I am far more hesitant to agree. Besides the fact that the organization has received TONS of corporate & billionaire funds, as well as all the corporate media coverage, government support, etc.
The founders are admitted Marxists, and generally the supporters I see en masse are the same folks out chanting for cops to be the only people with guns, supporting authoritarians both left & right, paying their taxes, and otherwise supporting & promoting the status quo as a whole.
If BLM was pushing to abolish the police, and stop charging people the "taxes" for them, that would be one thing... but they're not. Most of the message is about replacing "racist cops" with "woke cops" - and the Democrats have already begun using this as a means to bring the UN in to run the police.
As long as the state exists, oppression will be the norm. Anything that doesn't address the root problems of institutional violence, is at best shuffle chairs on the Titanic, imho.
Just published this piece because I feel like I laid out my stance on this pretty well in a FB conversation the other day.
