I can’t really think of a reason for that as Reddit is hated somewhat equally by “both” sides of the spectrum. It’s just something I find interesting.
I mean yeah. Being only English speaking with gringo Spanish doesn’t let me understand memes in German or any of the other various non-english speaking magazines lol.
English is the defacto lingua franca though. Particularly on the web. The diversity I’ve seen still heavily leans English, and western, which makes plenty of sense.
