If you only see American posts. then make one about which ever holiday you want. like I did! I didn't see a post about my holy month. so I made one and it caught on along other people as they did too

I often see posts about Islamic holidays and observances.

Not really most of the users I've known weren't from the U.S @BaconEggs

MURICA!

Hmm

Americans are simply to patriotic that's all

Because most of us originate from the United States.
