“Would you invite a potential den of vipers to move into your neighborhood?”
You can’t stop these vipers according to the First Amendment which gives equal rights to the good, the bad and the ugly. We claim that our freedom comes from God but our laws are written to please man, only.
That's a matter of opinion.
It shouldn't take much effort to demonstrate that islam is not a religion in the same sense that all the other major religions are. Until it is, it goes beyond ugly, and does not merit First Amendment protection.
Put another way, would a new religion be acceptable in the US if, central to its tenets is the cancellation of the Bill of Rights and every Constitutional Amendmentment since 1796?
I don't think so!
