Sorry I haven't read through all the other replies.
My feelings on it are this:
It makes me sad to see other people disrespected number one. Some have been downright cruel/mean and demeaning on some of the other forums when this subject comes up.
If Parelli or (Fill in the Blank Trainer) doesn't agree with you or your methods, there is never a reason to be rude or to throw cheap shots with glee.
I wish those that don't agree would stay out of the post unless the subject asks directly Anyone want to make fun of Fill In The Blank Trainer. Which would be of course childish.
There have been plenty of times I was really interested in reading about Parelli for an example and learn more and had to stop because of bickering.
I don't know when it became politically correct to bash him or anyone's methods, especially for those who are having success with those methods or are just intrigued with them like me.
