I'm human, therefore I'm racist. Suppressing innate racist tendencies is part of modern life. I've grown up with stereotypes as many others and my young life 'racism' as a Dutch kid from (grand) parents who survived WW2 was directed at Germans and Russians while the USA was this wonderful nation that could do no wrong. (Canadians liberated our town so they're even better!) Later the the blame game was directed at Polish and Turk immigrant and migrant workers. Chinese were fine since everyone liked their food (culturally appropriated of course)
My mother was a contradiction by herself. She worked for refugee organizations while often uttering borderline racist remarks over the people she volunteered to help. The line between cultural behavior, stereotypes and racism often got blurred. My grandfather (father's side) didn't hide any of his racism, including against my mother (Who was born in Indonesia. She fled with her parents from Indonesia after her younger sister, before my mother was born, died in a Japanese concentration camp, during the Japanese occupation of the Dutch East Indies, where my grandmother was held) My grandfather (father's side) spend most of WW2 in a German labor camp.
We have it easy nowadays.
