Oh, Miller has been mean plenty of times.
Everybody can be perceived that way at times depending on a point of view. Especially anybody who uses humor to make a living. But I prefer to focus on humor that isn't mean. People like Carol Burnett and her crew, Johnny Carson, Jay Leno, et al were sometimes pertinent to the news of the day or the national discussion at the time and they almost all used stereotyping, but they were never malicious, hateful, and/or cruel. I think Miller belongs with that genre more than the mean group.
