It’s quite possible the black friend won’t be all that knowledgeable on the academic definition of racism. POC/women/LGBTQ people don’t all have perfectly refined social justice opinions.
You’re right, but that’s not the point. Anybody can look up the academic definition of racism, even white teenage girls.
My goal was to whack them upside the head with their white privilege. The answer was deliberately meant to make the girls uncomfortable. It was a challenge, one that would force them to think about race in the context of their interpersonal relationships.
Honestly, what are they odds they even have a black friend?
