It is great that this is being addressed. I think English is a language which has been evolving over time. Especially in the colonial era, the language spread and a different branch of English emerged. A lot of words from English became mainstream in local languages and a lot of words from local languages made it back to English.
However, the dark underbelly of this phenomenon is that there are some serious racist undertones that come with this. Some words are "proper English" because it came from specific parts of the world, meanwhile similar words from other places are "Wrong English".
Certain speakers have accents that are "beautiful" and rewarded even if they completely butcher the language, it is completely understandable and held in high regard. Meanwhile others are considered "funny" or "stupid" and the speaker's intelligence gets questioned because of the accent.
As a non native speaker, I've had so many experiences where my intelligence is insulted and get shut down, because of my accent. Meanwhile the French guy next door gets applauded for saying the same thing again and gets a promotion. Language politics is real and it has severe consequences.
