I didn't say all of Generation Z. I said 90% of the white ones. If the generation is 55% nonhispanic white that'll be just under 50% of the total number of generation z will be nazis
You do realize that women exist, right? And that they're about half of any of the demographics in question. And that a bunch of racist trolls on the Internet =/= white "Generation Z" males.
While Trump has pretty clearly attracted some very disturbing forms (far-right) politics and thus, has brought them into the mainstream, most of Trump's voters aren't Nazis - they're Republicans. Hence, them voting for the Republican Party's presidential nominee. This really isn't that complicated.
