I'm not sure Vester is "appallingly racist" because his manifesto, unlike Root's, has no central point, but is reactionary paranoia to things that do exist (Root's race war crap), and probably don't (being trolled by watermelons). Vester seemed to think everyone (including black men) was out to get him because he was gay and was black, he thought that Root started an actual war, and he would respond, not by going after all white people, but people that specifically were out to get him in the past (in his own head), while at the same time, praising other white and Asian people that killed a bunch of people.
There are differences between racist actions, racism, stereotyping, and reaction to those actions. Racism is believing that many or all members of a race share a stereotype by default just due to the color of their skin, or hating people strictly because of the color of their skin.
Vester thought EVERYONE was out to get him (which is typical for people with certain brands of mental illness), and SEEMED to target his victims based on personal relation as opposed to just for the color of their skin. He didn't have a coherent focus at all and only singled out Root in particular in that quoted statement as opposed to consistently talking about white people as a whole. Were he targeting random people, it would lend better to him going after an entire race in general, as of now, it just aligns with generalized reactionary paranoia.
