ISIS (like their fellow Muslims in all majority Muslim countries) are like the Blue Meanies without the charm.
The Blue Meanies, you may recall "hateth everything that maketh music."
They are also like the Snapping Turtle Turks.
No, much worse. Those were cartoon characters.
Brits are being terrorized in UK. Not surprising since they are disarmed & held liable if they defend themselves. Not so much the case here, if you get my drift.
