Liberals seem to think "racist" is the be-all end-all of insults and applies anywhere and everywhere. "You don't like ketchup!? You racist!" or "You prefer Ford over Chevy? Racist!!!" Yes, 99.999999% of their uses of the pejorative "racist" are at least that silly or more so. The only racism I have seen in the last several decades has been coming from the left, basically directed at me, a middle-aged white guy. Liberals will attribute all kinds of traits and beliefs to me based solely on my race. They never seem to connect the dots - that making assumptions based on race (as they do with me) is itself very racist.
I always thought that the definition of “Racist” was “A conservative who wins an argument with a liberal”.
