plot twist: he was.

it harmed his own culture everytime a tourist mistakenly believed theyd learned about his culture by experiencing a trope.

it harmed his sense of self to lie about it.

it harmed the culture of those he was immitating, not only by making a mockery of it, but by potentially crushing their own attempt at doing the same thing by being a direct competitor.

it was also entirely understandable why he would do that in an attempt to bring in funds to help himself and his loved ones.

edit: its also harmful to the tourists, and every other marginalized group they ever interact with, by way of reinforcing their own stereotypical beliefs when they were potentially trying to learn for fucking once. just saying
