There's elitists in every style. Karate guys will say the exact same thing about body mechanics, correct alignment, foundation, etc, except they believe that the Japanese or Okinawan way is the most correct and beneficial way for the body to move in order to produce the most strength and power, and that Chinese martial arts are wrong. And I'm sure the people who practice the "southern folk stuff" feel the same way about their styles' mechanics and postures. Every style thinks it is the most correct way. If it's an older style, it is the correct way because it came first and has been practiced for centuries. If it's a newer style, it's the correct way because they have made improvements over the years based on experience and education. So what style has it right?
Of course, if you don't devote enough time to anything, you won't have it "right" no matter which style you're trying to represent.
