Fox News host Jesse Watters at the 2021 Student Action Summit, hosted by Charlie Kirk's Turning Point USA at the Tampa Convention Center in Tampa, Florida on July 19, 2021

After MAGA activist and Turning Point USA founder Charlie Kirk was fatally shot in Utah on Wednesday afternoon, September 10, a long list of centrist Democrats, liberals and progressives wasted no time wholeheartedly condemning the attack — from California Gov. Gavin Newsom to former President Joe Biden to Sen. Bernie Sanders (I-Vermont) and Rep. Alexandria Ocasio-Cortez.

Former MSNBC host Mehdi Hasan, who is originally from the U.K., tweeted, "Charlie Kirk called me a 'lunatic' and a 'prostitute' and demanded I be deported. Nothing, nothing, justifies killing him, or robbing his kids of their dad. We don't know the identity or motive of the shooter but murder can never be the response to political disagreements."

On Fox News, however, far-right host Jesse Watters had a threatening tone when he called for retaliation against Kirk's critics.

Watters told viewers, "They are at war with us, whether we want to accept it or not. And what are we going to do about it? Charlie would want us to put as much pressure on these people as possible….. This is unacceptable, and it has to stop. And it has to stop now. And everybody's accountable. And we're watching what they're saying on television and who's saying what. The politicians, the media, and all these rats out there. This can never happen again. It ends now…. This is a turning point."

Watters called for the right to "avenge Charlie's death" — a comment that journalist Pete Twinklage found especially disturbing.

On X, formerly Twitter, Twinklage posted, "this is spectacularly dangerous rhetoric. the Murdochs need to bench Watters immediately. vowing to 'avenge' Kirk's horrific assassination instead of calling for calm is beyond irresponsible. the country is a tinderbox and this lunatic is juggling dynamite and matches."

Watters' comments are generating a lot of discussion on X.

New Jersey-based Kim Hurdman tweeted, "Why would the Murdoch’s bench him? They installed him. The entire network promotes this mindset and ideology. Telling people their political opponents are enemy[.] They spent 40 yrs getting fabulously wealthy telling older white pp who to be afraid of and who to hate. Get real."

Journalist Jessica Durkin posted, "Meanwhile MSNBC is apologizing up and down because Matthew Dowd said the truth on that channel that Kirk speaks hate."

U.S. Marines veteran Gene Frenkel tweeted, "MSNBC fired Dowd.. Watters deserves the same."

Another U.S. Marines veteran, Paul Nun, commented, "Jesse Watters made an entire career around stoking division. He failed to mention the Republican terrorist who murdered Democratic politicians a few weeks ago."

X user Martin Judd remarked, "Murdochs have just announced the most radical far-right son will run the place. So he is not going to be of any help."

Journalist/author John L. Valentine wrote, "This punk isn't going to do anything but run his mouth. He's a TV warrior. Brave behind his desk. He'll leave the violence he's trying to incite to others. His call for more violence won't end the violence. It'll only exacerbate it."
