It's really odd that people on HN see the world as west vs. Slavic countries.
The world is MUCH bigger than that, and telegram has much wider spread than that. But yes, twitter spaces is tiny fringe space even in the "west"(a term that always bothered me given how the world is round, and how Australia, New Zealand, and Japan are somehow part of "the West").
For what it's worth, when I hear "the West" I think of what would on a global, historical scale be known as the "far west", i.e. mainly north and western Europe. (The "near west" would be the cultures just to the east of the Mediterranean, I suppose.)
I would never bunch Oceanic or Asian cultures in there.
I'm surprised to hear other people use it in a broader sense. At some point one is talking about cultures that are so different it's no longer meaningful to generalise across them.
I suppose that's because they are heavily influenced by western European countries. Two of the countries you mentioned are part of the British Commonwealth.
Why not simply say "Health" then? How is cultural assimilation any better than a phrase that has not had religious connotations for a century and a half?
