There was nothing new said here so I don't know you're talking about anybody waking up. Black people voicing their anger with the local political structure at events like these has gone on for decades.
This whole talking point of black people are brainwashed by white liberals has always been bullshyt. It is propagated by the right, and quite condescending because it assumes black people are ignorant and gullible and don't know anything better than following whatever the two boogeymen Al Sharpton and Jesse Jackson tell them.
Black people have never been gung ho Democrats who love white liberals. We vote for them because the alternative is Republicans
