Right, but that's not my point. You seem to suggest that his argument is that MSG allergy doesn't exist because some people's belief in it is racist ("does COVID-19 not exist, because somebody called it Chinese Flu?").

That's not his argument. He argues that it doesn't exist based on the fact that people who claim to be allergic don't suffer ill effects from other MSG-containing products. The comment about racism is secondary, it's not the basis of his claim that the allergy isn't real.

Some people who claim to be allergic don't suffer ill effects, and some do. This effect is very well known for other fad allergies, such as gluten intolerance. The existence of "gluten intolerant" people who eat cookies does not preclude the existence of celiacs.
