Most people in America are basic honest people but if you live there your house/car might get robbed one day. Does that mean that everyone in the USA is dishonest? Would you find it insulting for someone to say that about all Americans? You seem to have made friends with no one in one of the friendliest places on earth.
Are you familar with the book "Ugly American"?
Would you consider getting counseling and apologising to the many fine people who live on this island?
