No, but it's a problem and having the public discourse and criticism shut down is an offence to the American citizens that have lost their lives to Islamic terrorism.
The problem is when you have super-Christians like Ted Cruz harping on the phraseology, he's not doing it to better identify a threat, he's doing it to further entrench a narrative of good versus evil and to proclaim his religion as morally superior.
When you allow the religious nuts on the right to exalt their religion in an official capacity, it basically means the government is officially condemning one religion and praising another.
Which is exactly what ISIS wants. They want the US to be synonymous with Christianity and they want themselves to be synonymous with Islam. What the left is attempting to do is to dispel that notion while our conservative Christian Right is diving headfirst into it.
The left is being forward thinking in recognizing that you cannot destroy ideology, the right is being reactive and thinking that they can wipe evil out here and now and something else won't immediately take its place.
