you've got to consider that to a lot of these people racism "isn't real" because their bar for what qualifies as racist is set incredibly high. "how could that be racist if it's true?"

you can see a similar anti-trans sentiment in the people who defend jk rowling. "she's just saying gender can't mismatch assigned sex, how could the truth be transphobic?" nothing could ever be transphobic or racist or whatever to these people when they think very concept of being bigoted isn't legitimate
