As a benign example, eating food with your hands rather than utensils. In some cultures this is rarely ever tolerated, in others it depends on the food item, and in others still you might always eat with your hands. These will be at odds and you have to decide what is OK to shame and what isn’t.
I think we as a society bias against shaming in seeking inclusivity, but some things can be lost along the way as well. To use the eating example again, eating with your hands instead of utensils may be more likely to spread disease (or maybe it needs to be coupled with a stronger shame against _not_ washing hands). I don’t know what the right approach is to strike a balance here in a multicultural society.
