Ayers says he has been the target of hate-mail.

He also says that he is often quoted as saying that he has "no regrets."

"This is not true," he writes at his Web site. "For anyone paying attention _ and I try to stay wide-awake to the world around me. . . . Life brings misgivings, doubts, uncertainty, loss, regret. I'm sometimes asked if I regret anything I did to oppose the war in Vietnam, and I say, `No, I don't regret anything I did to try to stop the slaughter of millions of human beings by my own government.' Sometimes, I add, `I don't think I did enough.'"

"This is then elided: `He has no regrets for setting bombs and thinks there should be more bombings . .'" he writes. "I encourage people to argue, to agree or disagree, to discuss and struggle, to engage in conversation."
