The good news is that most Americans are tolerant of mosques even in the middle of the "Ground Zero mosque" controversy.
A Pew poll in late August asked which of these two statements you agreed with more:
"Muslims should have the same rights as other groups to build houses of worship in local communities"
"Local communities should be able to prohibit the construction of mosques if they do not want them."
62% agreed with the first statement, versus only 25% with the second.
