The Goq
Making fun of people or their accent is racist. Making fun of a language isn’t racist. When making fun of the language like in the above jokes the humor is impersonal and harmless. Listen you can disagree but if you look over the above jokes they are very innocent and I don’t see why anyone would feel insulted by them. Again we aren’t making fun of Chinese people.
Google the word racist and see if the definition fits your belief.
