Edit: Because I’m genuinely loving the downvotes
First off, you had 5 down votes, which makes it obvious you’re trolling.
But for those five it’s likely:
It’s because you’re trying to use semantics to “dunk” on an entire country, and it’s not even original, and still not even right.
It would be correct to phrase it:
The first pope from the United States of America
But pretty much every country has a long name that’s shortened down to one identifiable word.
Its very hard to believe anyone would hear:
The first American pope
And genuinely believe that includes anyone born anywhere on the continents of North or South America.
99.99% of the time, it’s someone trying to troll Americans, it’s not as clever as you think. And immediately complaining about a handful of downvotes makes it incredibly transparent.
As an open practitioner of pedantical semanticism, my people are no stranger to persecution.
