What is racism? To many on the left it now simply means that you are someone with whom they disagree. If you are not on board with their identity politics and white guilt, you are a racist and a fascist, and what ever other vulgar name they can think to call you. In other words, it really doesn't mean anything when they do that.
A typical dictionary definition would be: prejudice, discrimination, or antagonism directed against a person or people on the basis of their membership in a particular racial or ethnic group. For many years what was meant by racism was to ascribe an attribute or attributes of the group to an individual based solely on the person membership in the group. The left must not use this definition in any way now, for they commit this injustice all the time as a matter of course. For example Joe Biden once told a black man that if he did not know who he was voting for between Biden and Trunp the man was not black, as if a black man can only vote for him. In Biden's mind the man is black and all blacks must think a certain way. In his deranged mind blacks are not individuals who can think and decide independent of there race. The liberal media gave Biden a pass on this and nothing much was ever said, but this is the truly damming racist thought.
