After the Orlando attack, Obama ranted that it did not matter what we called Islamic terrorism. "What exactly would using this label accomplish? What exactly would it change? Would it make ISIS less committed to trying to kill Americans? Would it bring in more allies? Is there a military strategy that is served by this? The answer is none of the above. Calling a threat by a different name does not make it go away. This is a political distraction."
The "Islamic terrorists by any other name would smell as sweet" argument is the last resort of the losing side. It dismisses the whole issue as a matter of semantics with no bearing on the real world.
And that's a neat rhetorical trick for the political side that relentlessly refuses to acknowledge reality.
