1. Most native English speakers are in the US, so the accidental assumption that someone is American is more often than not correct.
2. The internal voice that reads text to me has a generic male American accent.

In other words, if you found yourself in a dark room with a thousand English speakers who all sounded like Jesse Pinkman, what country would you assume you were in?
English is the dominant second language in the world.
That's weird and pretty interesting if your own accent isn't a male American accent.
But that's my opinion.
What else would this imply?
This is a dumb observation.
US people needs to stop pretending the USA are the only place that matters on earth.
