Exactly the same could be said for any branch of the martial arts - pick MMA, or Karate, Jujutsu, Wing Chun, whatever you like. Start searching online for videos and arguments for why their style is the best, and you will see exactly the same thing. We seek the evidence which supports our own belief systems. And it is worth remembering the real purpose of all these videos on YT is to make money from repeated views. The controversial arguments and viewpoints get the most views, and make the most money - don't be so easily fooled by the internet, it does not the represent the reality of life.
