I disagree, IMO those who would wield the power of the government to enforce their opposition to the mosque are ignoring the constitution, but they are not in total all bigots.
These same people, almost in total unanimity (except apparently AHZ who thinks that the religion should be entirely outlawed due to the militant radicals associated), agree that they have every right to build a mosque, just "not here"...
Let's say that some abortion provider got attacked by a Christian who killed many people there, then a church who was against such actions taken by the perpetrator wanted to build a church right next door. Those who didn't want the church "here", but were not against the church being built elsewhere, would they all be "bigots"?
