8. Isaac Hayes // “Chef” on South Park
In 2006, Isaac Hayes wanted to leave South Park after nine years of voicing Chef, as he was deeply offended with its creators, Trey Parker and Matt Stone, for criticizing Scientology. Hayes, who has been a Scientologist since 1993, asked to be let out of his contract with South Park. Chef was killed off in the season 10 premiere.
"There is a place in this world for satire, but there is a time when satire ends, and intolerance and bigotry towards religious beliefs of others begins," Hayes said in a statement. "As a civil rights activist of the past 40 years, I cannot support a show that disrespects those beliefs and practices."
