Add openly gay actors George Takei and Cheyenne Jackson to the growing list of celebrities weighing in on Tracy Morgan's anti-gay comedy routine.

In a routine delivered last weekend in Nashville, Morgan, the star of NBC's 30 Rock, condoned anti-gay bullying and said he would stab his son to death if he found out he was gay.

Jackson, a 30 Rock guest star, said he was disappointed by Morgan's actions.

“I am disgusted and appalled by Tracy Morgan's homophobic rant,” Jackson said in a statement provided to gay glossy Out. “The devastating repercussions of hate-filled language manifest in very real ways for today's LGBTQ youth. I've known Tracy for two years, spent many long hours with him on set, and I want to believe that this behavior is not at the core of who he is. I'm incredibly disappointed by his actions, and hope that his apology is sincere.”

Takei, who is best known for playing Sulu on Star Trek, criticized Morgan in comments made to Hollywood website The Wrap.

“When I first learned of it my blood started boiling, but then, the more I read it over, you know, he's a sad, strange man. He's an African-American who has been subjected to bigotry and hate before, and for him to be perpetuating that, he must be an insecure guy,” Takei said.

“It's really kind of sad to see that and to talk about violence -- kill his own son if he turned out to be gay,” Takei said, before joking, “His father should be very careful: He might be the next victim of a killing rampage because he gave him the name 'Tracy.' It's a very lacy kind of thing, poor guy. Maybe that contributed to his insecurity and hence his homophobia.”
