Many generations later, some British are still feeling butt-hurt over the pranging they took at the end of American colonist gun barrels.

Piers Morgan seems to be one of those that can't quite get over it. But he does appear to have an elemental grasp of the logic behind Second Amendment to our Constitution: 

"I’m British, a breed of human being who burned down the White House in 1814 and had to be forcefully deported en masse, as no American will ever be allowed to forget – Special Relationship notwithstanding.
It’s no exaggeration to say that America’s unique fondness for guns pretty much got cemented by hatred of us Brits and the War of Independence."

This guy is nothing more than an asshole hoping his dubious, over-the-top behavior will pass as something controversial. Just another entertainer looking for ratings boost.
