Ok ... let’s for a moment accept that white people should not make traditional foods of indigenous Mexicans. Cultural appropriation and all that.
But, the same rule should apply to indigenous Mexicans. So: no flour tortilla, no beef, no chicken, and no onion should be allowed in the authentic, indigenous Mexican tortilla. Also, cheese is a European invention, so that’s ruled out as well. No cilantro, either. Because all of these ingredients — which account for about 90% of the typical burrito — originated in either Europe or Asia.
A recognizable burrito is pretty much impossible if limited to ingredients that are native to the Americas. It would only be a genuine, indigenous Mexican burrito, untainted by Mexican appropriation of European and Asian ingredients, if it were a corn tortilla stuffed with fish or meat from a nutria or other rodent, tomatoes, and peppers.
Winner, winner, chicken dinner!
