While I can somewhat agree with some of the things he says and does in this video, I cannot accept the fact that he feels the need to verbally abuse another person and put down their way of training because it differs from his own.
I agree with Bear L on their comment in regards to promoting and explaining his methods. There are plenty of people that I do not agree with on certain subjects that I find my methods to be better. To promote how I do something, is it needed to bully or target others? No.
I think that it is great that he would like the public to use more positive reinforcement when dealing with their dogs. Wonderful. However, 100% PR
does not necessarily ALWAYS work with EVERY dog. Just as with every subject regarding dogs and animals in general, what works for one person and/or dog may not necessarily work for another. It doesn't matter the breed, age, gender, location, background, history (I could go on and on regarding personalities and demographics) are all the same of the animal(s) in question - they will not necessarily respond the same to the exact same methods.
I think that this man, in general, regards himself much higher than he should. I will repeat that it is wonderful that he is attempting to promote positive reinforcement as the 'new training style' (even though, as others have stated, it's not new - just being reintroduced as such), but to put himself on such a high pedestal and to shoot others down into the gutter is not right in my opinion.
As a side note, I'm not a huge fan of how much he says you have to really be down on the dog's level, in it's face, to make it concentrate on you while doing a task such as standing on the guy's back. Most dogs aren't exactly comfortable with humans being in their faces and right at their level as such.
EDIT: Also as a side note, from the episodes of CM's show that I have seen, the dogs in question are usually the outliers of dogs in society. They are the ones that have a bad/abusive past, have some sort of major training issue (and I don't just mean "my dog likes to jump on me, it's annoying"), or can be labeled (by the standards put forth by the SPCA and other humane society organizations) as aggressive. The ones that this man seems to be talking about are your run of the mill family pet that someone either wants to train to have basic manners and obedience and without such would just be an annoyance or frustration, but not anything dangerous or extremely disruptive to society. I could be wrong, but from this video and what I have seen of CM those are the main differences in the types of animals that are being dealt with. If CM were to take an 'average' dog that was just needing some basic manners, I doubt the response from the public and this man on CM's training methods would be as outrageous (because I doubt CM's methods would be as harsh as they currently are when dealing with the majority of the dogs that I have seen on his shows).
Anyway, the above is my personal opinion, so please refrain from dissecting it and making me out to be a bad person if you feel it necessary to respond to my reply.
