That's the definition of racism: Ascribing to each individual attributes of the group. What more proof do you need that he's racist, and who would question that that is the viewpoint of the entire democrat party?
You know what? Maybe there is another way to attack this problem. What if BLM has an argument regarding systemic racism. All they have ever been a part of is the Democratic System. We see the Democratics racism so of course they do too. They live it. BLM are rioting in Democratic strongholds. Heck, if they are saying they want to burn down the Democratic system because it’s totally racist, maybe I should be helping them?
