I believe the poll shows the tolerance level of the left. If we were talking about the muslim coalition than the poll would show great approval from the libs.
No, a good liberal would despise all religions, though admittedly the christains are far more dangerous than the muslims.
Any good liberal would accept the role that religion can play in the lives of each individual. As for who is more 'dangerous' ANY religion taking to its fundamental extremes whether you are Osama or Fred Phelps is inherently dangerous.
I would much prefer a moderate Muslim to an extremist Christian.
