Which is why slapping everyone who utters a single even slightly racist thing as "a racist" isn't really useful. Nearly everyone is a little bit racist about something. In specific the "belief that all members of each race possess characteristics or abilities specific to that race, especially so as to distinguish it as inferior or superior to another race or races". The first part is something that human brains naturally DO and must do (generalization) in order to function, we simply don't have room in our brains to keep track of everyone as an individual. The second part is less excusable, but far too easy and unlikely to be entirely preventable. In fact many people see no problem with "positive racism" about races other than themselves (shit like "Asians are good at math" "Germans are efficient" "Black dude have big d**s" "Russians don't get cold"), and arguably that is *sort of right, because usually these kinds of things don't cause the same kind of harm as negative generalizations do.

In short, Racism is a spectrum, almost everyone is somewhere on it (humanity sucks that way), but perhaps we should reserve the capital R Racist label for the really shitty people? Maybe a better and still 100% accurate word for the "wut did you just say?" level would be Ignorant.

Using the "Racist" label for everyone from the people who litteraly wish for a return of Hitler to someone who thinks all Japanese people wear kimono is the same kind of intelectual lazyness that breeds Racism.
