It's got nothing to do with 'tolerance', numbnuts.
We open our arms and 'tolerate' peoples of many different religions, cultures and races.
However, what made this country great was the 'melting pot' (ever heard of that term?) that it is (was). Melting pot means assimilation into the established form of government, culture and, yes, religious and social values.
Multiculturalism is nothing more than left wing PC crap that is leading to the balkanization of the country.
So, get your head out of your liberal butt and try thinking once in a while. And maybe read a little American history in between reality shows.
