Why? Guilt, jealousy, and/or past history. Guilt: I don't want to change, even though I "should", so I blame the people trying to get others to change. Jealousy: I had to change on my own, and it was hard, so I think people who help others change easily are somehow cheating. History: I believed a guru, did what he/she said, had a horrible outcome, and tar the entire industry with the same brush.
