Farsi? To flip it around a bit, imagine a Russian majority telegram channel dedicated to the upcoming American civil war. What would you think about that? Well, how is an English majority subreddit any different?

Are you maybe accidentally White Knight-ing here?

eg getting upset on someone else's behalf, for something that doesn't actually bother them

I don't have any involvement or personal connections. It just looks weird? Honestly, I want it to be true, but I'm also old enough to remember the whole twitter revolution that was totally going to happen a decade ago but didn't. In that subreddit, what is the proportion of westerners to Iranians? I have no idea, but the one signal I have is that the posts are majority English. Which is depressing. It's like when there's a local election and reddit is a huge echo-chamber that's 100% convinced their chosen candidate will win, who subsequently gets crushed. Is this any different?

What language do you think South Asian diaspora communicate in?

The internet/computers were never designed for Farsi. And the situation was way worse for phones before smartphones. It’s only recently that efforts have been made to make it possible to communicate via Farsi, Arabic, or South Asian languages. But it’s still extremely hard.

Russia has a significant Russian only computer development program, so communicating over devices via Russian is more common. East Asian languages have spent a lot more time/energy finding ways to communicate via their own languages, and even there, the most popular text communication language is one which uses English characters. Also, English is spoken far less than in a country like Iran, which has a highly educated populace, that until very recently was very integrated with the English speaking world.

Communicating in English is absolutely obvious for such a diaspora.
