English simply doesn't have the sounds present in the word "Español". Look up the transcription. Sounds /e/, /ɲ/, /a/ are not present in English. Is it really the same word if you mangle it and replace those sounds with similar ones from English? And this is an example from romance language. Words from less related languages will be translated even worse.

And even if you do, historical development of languages will lead to those words drifting even more apart, resulting in differences not unlike present today.

That's the 'New York' of British English, by the way. American English doesn't pronounce a palatal approximate preceding the long 'u' sound, and in Irish English 'new' doesn't contain a long 'u' at all—because, of course, pronunciation is accent-dependant.

OP didn't mean this literally. They speak from a strong belief in the importance of cultural education and the applied respect for/engagement with world cultures, through the use of native language, for example. This idea is incredibly common, and derives I assume from the global history of language bans as a tool of oppression.

So, yes: 'something something colonialism'. Scores of languages have been crippled or lost by colonial "assimilation", and engaging with other cultures through language is a simple and meaningful way to show allyship and respect.

I'm Australian: In my country we learn and use aboriginal languages to acknowledge the continual history of our country and its indigenous peoples. In my country, accepting and embracing aboriginal languages is a massive part of reconciliation. My country and its people live through this issue every day, which is why I'm rambling on about it, and why I support OP's stance on this topic.

It's rude. You're making someone take their time to read something you couldn't bother to write. You're telling them they were so unimportant you couldn't be bothered to actually take the time to say something yourself. And frankly, you're lying about it while you're at it.
