Look, they could be howling for the immediate and complete nuclear destruction of the United States. How does that justify burning down the neighborhood mosque?
I should add that the North Koreans have been howling precisely that for 50 years, and yet I don't see you calling for Koreans to be shipped back overseas. Or do you?
Did I advocate the destruction of a mosque? Or the killing of Muslims living in this country?
For one reason most of the "neighborhood" mosques are built by Saudi government money. Instead of allowing mosques to be built in the first place, we need to get far more selective in who immigrates to this country --- with all the people in the world who would like to come to the USA, we certainly don't need muslims, we should limit immigration from muslim countries to non-muslims seeking religious freedom or to ex-muslims who face the death penalty for wishing to leave the religion.
