Thank you very much @sigmajin!

You have used the words "migrant" and "refugee" incorrectly.

I am not a native speaker!

Migrant means a person who moves from place to place, continuously.

Maybe a case of "false friends". I was under the impression that "migration" is the umbrella term for all kinds and reasons and modes of wandering...?

The word i think youre searching for is expatriate, which means broadly someone who has left the area native to them

Exactly! Who really feels "at home" on Facebook or reddit though?

unfortunate political connotations

Oh, I love those, but...

...to each his own...

;p
