You're confusing a lot of groups together here. Trying to influence the NYC mayor and public opinion is very different from bribing Democrats as a whole. IIRC the mayor is quite right wing too, like a Manchin type.
There's also a significant difference here -- Trump is saying what he would do. You're claiming what Biden has already done, and your evidence is a public statement that he made -- which don't get me wrong, was a shitty one to make. You haven't proved though that Biden or Democrats as a whole told the police to do that and shoot with rubber bullets and painted them all as violent. In your own link, Biden makes a very clear differentiation between peaceful and violent protest, and he says the former is a bedrock American principle. Your own link contradicts what you're describing and doesn't support your claims. It says blatantly that Biden won't use the national guard, which is the actual enforcing power that the president has.
Come on, there's plenty to criticize Biden and Democrats on with Israel without making leaps and lumping everyone together. I have respect for a lot of the points and arguments you've made in the past, but this isn't it. This is just sensationalism not grounded in reality.
