We judge the world based on our own perspectives and our own
level of experiences. If you hang around groups with a lot of
English speaking Americans in it, you get a lot of people who
don't bother mentioning the country they're in.
If you're in a group of professors and students talking about
linguistics and there's a slightly heavier Russian population in
the group, they'll often drop the fact they're from Russia from
the conversations and just mention their cities and areas.
I think it's more due to group dominance than certain
nationalities though.
Then again, we're taught a peculiar thing in the USA - one of
our prejudices: We're taught, if someone is from another
country, we'll be able to tell 'somehow' by their accent or by
the words they use.
But online, there's few distinguishing factors from one country
to another in the words they choose.
So, our default is: If person writes "like an American", must be
an American. Also, we're NOT taught about American Imperialism
as a _current thing_. I only recently realized it myself. We're
taught that American Imperialism WAS a phase of the USA in the
19th century.
What we're NOT taught is that we're CURRENTLY in a phase of
American Imperialism.
