How does this differ from saying that women belong in the kitchen, or that being black means you rob people?
Stereotyping has, for my entire lifetime, until the past few years (trump I guess, until trump...), been something you'd only really see happening among the Republican types.
Now it's become almost an exclusively Dem thing...
I get the whole "statistically speaking" aspect (I have a LOT of neighbors with lifted ram trucks on very clean mud tires) of your comment, but that same logic is behind all the other stereotypes as well... How is yours good and theirs bad?
