First of all I wasn't around during the friction between CLF and WC. So it's not my fight. I have friends who do CLF. One is a Sifu. I was taught in the Marine Corps that a warrior should know the weakness as well as the strengths of an opponent. To ignore his strengths could get you killed.
I must make this clear. I'm a "martial artist" who just happens to specialize in WC. I'm not a "WC man". In my first tour in Vietnam we used M14s, my second tour we got M16s. We were also trained to fire AK50s and AK47s. What if your weapon misfired and there was an AK lying right next to you? If you weren't familiar with how to operate it you'd be SOL. The same goes for martial arts. If you stay in you own little box you'll get surprises from out side of the box. So a "martial artist" must be familiar with other systems and have respect for what other systems are capable of.
