The democrats participate in this export strongly too. Biden shut down a really important union strike. They are less overt about it, but go watch Malcolm X talk about foxes and wolves.
The Democratic Party too had problematic 'wealthy supporters' that influenced them away from a people's real needs. However, Biden's initiatives were probably the most 'socialistic' since FDR. And if the DSA and Bernie Sanders' aligned forces are finally able to force the Democratic Party back to their roots of FDR, then there is good chance we might still make it.
Really all the comments about "white moderates/liberals." The exact sort of people who forgot the Civil Rights movement, Labor Rights movement, and Women's Suffrage, and really every movement by a marginalized group to gain power from the mainstream were packed full of organized political violence.
Non-violent protests have a place. On occasion though, you need to hit the system where it hurts in order for it to take you seriously.
