I’ve literally never heard anybody in my life say this.
Look for a local charity vid from southeast Asia. Local people who make these huge portions of food for the impoverished are usually scooping the rice and curry with their hands. Normal people will see this and say “hell yeah glad they’re supporting each other” while a racist would call it dirty and make a white savior bit out of it.
Ya but I also think it’s ok to react to foreign cultures in a variety of ways. There isn’t one way we have to be all the time. If someone is grossed out by something they’ve never seen before then they aren’t automatically a bigot or racist.
If someone scooped up my rice with their hands I’d not want the rice. We use utensils for serving things and I’m sure other cultures have a variety of opinions about that. I’m sure I’d get used to it if I moved somewhere where it was normal.
