Americans really love some European countries. Mostly, we tend to not like the French, and a lot of that stems from how we think that they look down on us. Well, really, our men even like French women, just not French men. We feel like the rest of the world hates us, because that's what our media tells us, so we sometimes react accordingly. However, taking a trip to Europe and even learning European languages (like English! [joking]) is appealing to many of us. We especially mingle well with the British and the Australians (yes, I know they aren't European), but we also have affection for various other countries. Even German and Japanese media have made their niches here, despite how obsessed we still are with WWII.
As far as saying that immigrants should get out of our country, people are generally talking about Hispanics. It isn't the fact that people of other races are here (most of the time), it's that people that aren't legal citizens are here, not paying taxes and not speaking our language but still working our jobs and getting many of our benefits. That isn't to say I think they should go back to where they came from, so to speak, but that's the reason. Some people feel like their culture and way of life is threatened.
To be fair, there does seem to be two opposing and equally absurd assumptions that I see coming from the less enlightened. Some people think that all politics and government outside of the U.S. is stupid, and that we're the only country with any grasp of freedom. On the opposing side, many practically fall to the ground in praise of any foreign policy and political system that isn't American. Americans love to hate and love America.
) and many Americans do not have European Ancestors. And once again I?ve never heard any of us say that legal immigrants should go back to where they came from.
