Let me preface this by saying I am not (nor have been) a WC/VT (or whatever other name you prefer) practitioner. I have much respect for the style - just never seriously trained it. I've done some bits of various southern styles, but my main bread n butter is Northern Shaolin. That said...

My question for long-time practitioners of the art is this:
I've seen way too many MMA folks on this board as well as on others, youtube, etc. (including that now-famous clip of Rogan's) totally insult and dis the style. BUT you don't hear them calling out Lung Ying, CLF, White Crane, Northern Shaolin, etc. I'm not hinting that they think these styles are better, but I am dumbfounded at this - WHY? I mean are all these people to think "Kung Fu" = Wing Chun [only]?

Was there a WC individual who got into a famous MMA match and lost so they now dis the entire style? Or what is it?

Just curious why they pick on one particular style of TCMA? Why the grudge?

(Definitely not hoping to have my main style called out, but just curious why they're doing this - plain ignorance or something more)?
