As Samuel Johnson said, "When a man knows he is to be hanged.. it concentrates his mind wonderfully." When we get bloody proof that all religions are not the same and only one, Islam, is producing a strain of beheaders who revel in their butchery, it concentrates the mind. It will change who gets elected. Politicians will see advantage pandering to shock-concentrated citizens instead of to Occupy types.
Before leaving the topic, remember with sorrow that Americans live under a president who says after Muslim assassins murder praying Jews in Jerusalem:
"Islamic State’s “actions represent no faith, least of all the Muslim faith which Abdul-Rahman adopted as his own”"
