muslim countries have more of a right to tell us to leave their country, than we have to tell their immigrating citizens to leave ours. we are the country made of immigrants. we are the country that allows anyone to come and have a good life, assuming they follow our laws.
we have been through many periods like this. the irish-catholics before JFK was elected, black people were hated on throughout our entire history, the chinese during the early 1900s, the russians and/or cubans curing the communism era. all of these were based on misconceptions, individual people being used as an example for the whole race, plain ol' racism/bigotry, and of course ignorance.
