Is it actually "harmful" though? People are still going to Chinese restaurants as far as I know. The "harmful" adjective is being thrown around a lot, but it's never been very clear to me there is actual harm. People will cite things such as "violence against Asian-Americans has been on the increase!", but that seems entirely disconnected from some jokes in some sitcom.
