It's funny because some SJW types on Twitter are defending her saying she's "Transethnic" or some nonsense.
You do realize that basically 100% of the people peddling that line are right-wing 4chan/8chan/etc. trolls posing as SJWs for trollish purposes, no?
How would anyone tell? The idea that gender is flexible but that ethnicity is a stable category is in itself hilarious.
Is this an allusion to transgender people, i.e. Caitlyn Jenner? Because she did not "change genders." She has always been a woman. That's not flexible.
Race and gender are different things. They work in different ways.
