The way to deal with smug, elitist hypocritical limousine liberal NIMBY's is to put it in their backyard.
A state's or municipality's self-declaration as a "sanctuary" is a declaration that they want more illegal immigrants.

Off-season mansion rentals should be used to provide housing for the homeless and for illegal immigrants.
