This point is axiomatic. Those who argue against it are simply lying to themselves.
The "morality" of a given people is irrelevant to their right to leave.
The US Constitution acknowledges our "freedom of association" and therefore must also acknowledge it's corollary; The "Freedom of Dissassociation."
The right to leave is no different. It is sinful and tyrannical to force people to associate against their will.
Obama is forcing us to associate with massive quantities of Muslim immigrants, and third world socialist sneaking across our borders from Mexico/South America. I doubt any one of you would argue that this was not tyrannical.
I think most would argue that we have a right to NOT ASSOCIATE with these people, but the FedZilla will certainly drop a hammer on you if you refuse to rent or serve these people in your establishments, or refuse to put up with them in your schools.
Again, no one is arguing against your right to disassociate. The door is open if you want to leave. But you can't strip We the People of the United States of their national territory on the way out the door. Sorry.
