Well.
People are really wearing their bigotry on their sleeves with this one, then shining it up and strutting it around like a badge of honor.
To all the ignorant racist bigots in New York and in this country: Please understand that First Amendment to The United States Constitution explicitly states "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
There you have it - While the United States has no official religion- and as such is by definition secular- its people are free to pursue without restriction or sanction whatever spirituality or faith they choose, and are protected from all persecution for uttering, publishing, and publicly demonstrating their political or religious view whatever those may be.
It is this sentence of The U.S. Constitution, perhaps more than any others that sets the United States apart from nations where liberty is not held to be sacred. It is precisely the reason that the United States has been an asylum for political refugees from every part of the globe for over 230 years. It stands to reason that those who oppose this mosque for whatever reasons-pretended or true- are indeed expressing their disgust and contempt for this fundamental American Principle that is at the very heart and soul of America's greatness.
