Sounds like Sheen's been hanging out with Ted Nugent..

In his interview with Jones, Sheen repeatedly evoked violent images and ideas. He also derided Lorre in an attack that suggested anti-Semitism.

“There's something this side of deplorable that a certain Chaim Levine - yeah, that's Chuck's real name - mistook this rock star for his own selfish exit strategy, bro. Check it, Alex: I embarrassed him in front of his children and the world by healing at a pace that his unevolved mind cannot process,” Sheen said.

“Last I checked, Chaim, I spent close to the last decade effortlessly and magically converting your tin cans into pure gold. And the gratitude I get is this charlatan chose not to do his job, which is to write,” he said.

Saying he was told that if he went on "attack" execs would cancel the show, Sheen repeatedly referred to the showrunner as "Chaim Levine." (Lorre's birth name is Charles Levine.)

Sheen later went on to attack Lorre on TMZ, saying he "violently hated" the showrunner, whom he called "a stupid, stupid little man." Sheen challenged Lorre to a fight, saying "If he wins, then he can leave my show."
After the announcement of the series shutdown, Sheen fired off an angry letter to TMZ that read:

"What does this say about Haim Levine after he tried to use his words to judge and attempt to degrade me. I gracefully ignored this folly for 177 shows ... I fire back once and this contaminated little maggot can't handle my power and can't handle the truth. I wish him nothing but pain in his silly travels especially if they wind up in my octagon. Clearly I have defeated this earthworm with my words -- imagine what I would have done with my fire breathing fists. I urge all my beautiful and loyal fans who embraced this show for almost a decade to walk with me side-by-side as we march up the steps of justice to right this unconscionable wrong. Remember these are my people ... not yours...we will continue on together... Charlie Sheen"
