Sheen replied, "Seismic.""He didn't belittle anyone, he didn't demean anyone, he didn't embarrass anyone," Sheen said of Kirk. "He didn't go there to, like, be a smarty pants and make you look stupid. He was just like, Hey, man, OK, heres what I've prepared. Here's what I know, here's what I believe. Give me your side of it.'"Sheen additionally remembered his Sept. 10 podcast appearance with Joe Rogan and when they first heard the news about Kirks death.He and Rogan were recording an episode of "The Joe Rogan Experience" when the pair paused as staff alerted them to the breaking news."We go out into the lobby and one of his security guards says he just died," Sheen said.From there, Sheen and Rogan headed to a bathroom.

"It's so scary. It's so dangerous too, to celebrate or to in any way encourage this kind of behavior from human beings. He's not a violent guy. He was talking to people on college campuses."He added that Kirk "wasn't even particularly rude. He tried to be pretty reasonable with people.""Everything I saw seemed reasonable," Sheen replied.CLICK HERE TO SIGN UP FOR THE ENTERTAINMENT NEWSLETTER"He was a very intelligent guy," Rogan said. "Whether you agree with him or don't, and there's a lot of stuff that I didn't agree with him on. That's fine.
