It turns out that Donald Trump - hotelier and presidential hopeful - really wants to be a doorman, so he can stop entry of all Muslims into the US. His are the sentiments of a madman who's pandering to fear and ignorance, not the voice of a nation. (FYI - two of three Trump wives are immigrants!)
But the US - a land made up of foreigners - does have a rep for marginalizing each new wave of ethnicity as it washes up on shores. Despite this, people still come, and excel, often becoming pinnacles of "American" achievement. So Muslims are in good company. Check out a dozen examples to see our point.
