The author is exactly right. Political Correctness has already closed the debate. Unless this is somehow overcome, we are finished and "liberty" will eventually become universal "submission" to Allah.
Our Founding Fathers would be appalled at the state to which their legacy has degenerated. Every passing year our country resembles more the ancient Biblical Kingdom of Israel than the newly minted 13 United States of America!

Commentaries on the Constitution
The means that are being employed to advance the acceptance of and deference to Islam - demands for special public accomodations, the "flying Imams" circus in a public airport terminal, refusing to do the job they were hired to do, etc - are the dividing line at which the original intent of the Constitution to protect religious freedom stops. They cross that line of thier own accord and as long as they continue to do so, I for one feel no obligation to hold their religious beliefs beyond the reach of civil law.
