You're assuming that there must be so many people in this country who haven't visited other countries and experienced other cultures, societies and that's an unfair generalization. This isn't the early 20th century where tourism was confined to the wealthy, privileged and affluent visited other countries. How many millions of Americans actually visit other countries on a yearly basis? How many hundreds of thousands of Americans do you think will be visiting other countries in Latin America, Canada, or Europe over the next month over the Christmas holidays? It's very ignorant and misleading to actually argue most Americans haven't traveled or visited other countries and been exposed to other cultures, societies to some extent or another.
