sadly it's impossible to be both "not racist, nor sexist" _and_ against "positive discrimination". not sure how much more simple i can make it for ya. sorry.
no one is angry because one person of color or woman is rejected from a position; it's not a simple first-order investment but rather a structural, generational change and people are mad because folks in power are not (occasionally, and thankfully increasingly less) acknowledging that. again i know it's almost certainly too complicated for someone who is pro-structural racism and misogyny to understand.
and, it's not possible to be "racist" in the way that racism is used in this structural way against white people. white men are sadly still in a position of structural power and as such you can't be racist against white people (especially white men). sorry for your lack of understanding here as well.
