Really? Have you lost your mind, Senator McCain?
Let’s assume for a moment that indeed the words literally mean the same thing. So what?
We have all seen pictures of young males screaming “Allahu Akhbar” with raised weapons in the air. Sometimes they are celebrating the deaths of Americans. Other pictures show the celebration of civilian deaths around the world at the hands of terrorists. The specific circumstances differ, but we associate the words with the celebration of death, mostly of innocents.
Since you say the words mean the same thing, Senator McCain, will you please show us the pictures of Christians dragging dead people through the streets screaming “Thank God!” as an epithet? Maybe you have pictures of American Christians roaming their cities screaming “Thank God” when Hussein was executed. Surely you have some pictures of Christian suicide bombers screaming “Thank God” just before blowing themselves up and destroying life and property around them. Or pictures of hordes of armed Christians anywhere celebrating death with the words “Thank God.”
Until you show us that Christians use the words “Thank God” in the same way that others use the words “Allahu Akhbar” your saying that they mean the same thing is just silly. Our elected leaders saying silly things is not really a good national defensive posture.
