It's not about racism. At all.
Racism is just a tool to get them to where they want the world to be.
Just read Stealing America: What My Experience with Criminal Gangs Taught Me about Obama, Hillary, and the Democratic Party by Dinish D‘Souza.D'Souza makes the case that what he learned in his discussions with fellow felons during his incarceration is how well leftist propaganda fits the model of a confidence swindle. He now dismisses the idea of arguing with a leftist to try to convert him. The leftist “argument” is not truly an intellectual argument but a swindle.
I absolutely agree with that.
Unfortunately, some of the swindlers don't know it, and they think that they do have an intellectual argument. They are annoying, especially because they are relentlessly trying to be "correct" when I know that the real goal is just to rip me off. Correctness has nothing to do with it, whether they realize that or not.
