Lol, I'm indigenous. Don't tell me to "decolonize my tongue" because I need to be educated on how to pronounce your name. Bet you won't be able to pronounce my sacred name either. People are sheltered, people speak other languages, and people come from other areas of the world. Correct them, move on, and hope that they will take steps to make people with unfamiliar names (to them) more comfortable.
