I really like the National Memo's Joe Conason, but I don't understand for the life of me why any self-respecting liberal would agree to go on the air with Joe Scarborough. Here's what happens when you get on the wrong side of Morning Jihad and that foul nasty temper of his.

After reading a quote from Ron Fournier's latest screed, saying he doesn't believe that Hillary Clinton wants her emails from the State Department releases, Scarborough asked Conason to respond and very shortly after that things went off the rails.

Joe Scarborough Goes Off On Guest During Debate On Hillary Clinton:

A heated exchange broke out Wednesday morning during a debate about Hillary Clinton on MSNBC's "Morning Joe."

Joe Scarborough had been criticizing the Clinton camp for holding back emails sent from her personal email address while she was working at the State Department.

"It's what he said about the Hun, which is, 'They're either at your feet or at your throat,'" Salon columnist Joe Conason said, quoting Winston Churchill on Germany during World War I.

"So you're comparing me to Nazis," the MSNBC host responded. "That's great. You just used a Winston Churchill quote to compare me to a Nazi because you don't like the facts."

Conason explained, "There are times when you've been friendly to the Clintons, I believe you broadcast from CGI at least one time. ... Sometimes you like them, sometimes you don't like them when it's convenient for you."

"Oh no, does that make me a Nazi, Joe?" Scarborough said. "What are you talking about here? I am as transparent as anybody."

Conason tried to interrupt Scarborough to further explain his use of the quote, but Scarborough continued: "No, no, let me finish. You compared me to a Nazi, you brought up a Churchill quote when he was talking about the Nazis."

"No, I didn't compare you to a Nazi," Conason. "He wasn't talking about the Nazis, he was talking about World War I. [The Huns] were not Nazis."

Here's more from TPM:

MSNBC host Joe Scarborough went from zero to one-hundred on Wednesday morning after he became convinced a guest was calling him a Nazi.

The moment came, as many tirades do, in the middle of a debate about the Clintons. Guest and author Joe Conason made the case the Scarbrough, who has spoken several times at the Clinton Global Initiative, was hypocritical for going after the power couple for shady donations and Hillary Clinton's email server.

Scarborough didn't let the feud die with the segment; he tweeted about the exchange later on Wednesday:
