If you call this a great country,you should know this country is built on the principle that different people have different opinion and the Founding Fathers strongly believed in Voltaire's when he said
"I may disagree with you but I will fight to death to defend your right to a different opinion"
and it was used as a basis for US Constitution.

How could you then tell somebody to get out of this country because the person has a different opinion. Have you not learned anything by living in this country?
