Piers Morgan is having a busy evening lecturing Americans on the Second Amendment tonight, and he’s doing a stellar job of making sure everyone knows not only is he ignorant about principles of American constitutional law, he’s also a colossal jerk.

Morgan posted several tweets dismissing gun rights as something that should be limited to hunting and displaying an astounding level of misinformation about guns and how they operate.

Morgan told people to “try reading up on” the history of the Second Amendment, while interpreting the law completely backwards.

As many people tweeted at him, the Supreme Court of the United States explicitly held in District of Columbia v. Heller that “[t]he Second Amendment protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home.”

Morgan also made sure to make it clear that he thinks “ALL semi-automatic guns should be banned,” ignorant of the fact that this would include virtually all handguns.

Conservatives on Twitter attempted to educate him, but to no avail.

Then people reminded Morgan of the time that Ben Shapiro — a Harvard Law alumnus, so he knows a thing or two about the law — came on his former show on CNN and absolutely schooled him on constitutional rights. During that discussion, Shapiro had brought with him a pocket-sized copy of the Constitution, which Morgan dismissed as “your little book.”

Morgan’s response was to launch a petty attack against Shapiro.

Shapiro might be younger and shorter than Morgan, but he’s the one standing tall here as Morgan continues to get the basic facts of American constitutional law, guns, and how to conduct a Twitter debate embarrassingly wrong.

Americans fought the Revolutionary War so that the British would stop telling us how our rights should be defined. We can’t make them shut up on Twitter, but Shapiro had this sharp response:

UPDATE: Morgan continued to tweet, attacking Shapiro over his use of “inalienable” when the word used in the Declaration of Independence was “unalienable.” Never mind that multiple Presidents have used the word inalienable (including, as Shapiro points out, Jefferson, Lincoln, Clinton, and Obama) — the words literally mean the exact same thing and are interchangeable.
