Generally speaking when someone asks that question it is with an eye to disqualifying a speaker they don't want to listen to, on the basis of ad-hominem.

Latin America? "You're ignorant, you know nothing!"

China? "You're under their sway!"

America? "Hypocrite!"

I tend to prefer to simply not allow the discussion to veer in that direction, and keep people guessing if they must.

It lets others understand perspective a bit better.

Well, my English is pretty good and I'm from Latin America. I think that ought to give you enough of an idea.

You can't attack other HN users based on where they're from or reside—no matter how wrong they are or you feel they are.
