On the other hand, if you mean "world travellers", then yeah sure that is a lot more specific than just saying most Americans have traveled to some countries and that's it. BigDaddy just whole sale said these types never been anywhere and that falls part as a ethical/moral absolute argument.
Being a " world traveler" isn't the same thing as some or most Americans visiting 4-5, or maybe 8-9 countries and some wanting to label it as they haven't been anywhere.
