One thing thats important to remember here, is that many many folks who found themselves in a bad school or a school where they werent happy with the quality of training like Hanzou, tend to become very, very stubborn. They find something they like and become very rigid in their belief that their way is best,
There are a lot of people in MMA who wil bash TKD and Karates ability to fight even when showed fighters like Machida who is very much a Karate "Purist" in the cage with it being his main striking foundation. Or Spider Silva, Ben Henderson, and Cung Le who all use a lot of WTF TKD style kicks. Or back in the early days of Kickboxing, where point fighters from TSD, Karate, and TKD basically went straight into full contact bouts with boxers and folks from "Harder" styles.
There are many, many MMA guys out there who train in as many styles as they can and always seem to pick up something they like and feel they can use. When somethings been or is being used regularly in the cage and ring, and someone still denies it they're just stubborn. Some folks are just like that, trying to change their opinion would be pointless.
Folks poor experiences, or lack of experience to other styles in some cases, have given them a firm opinion. People here seem to be taking these differing opinions very personal lately hence all the animosity and frustration.
When many of us here use or have used our TMA training in the cage, ring, or in SD the idea that one needs gratification from someone on a computer screen is crazy in my opinion.
