Thank you for your kind words.
That phenomenon is connected exactly to what I was saying in my last post. The majority of people who have been exposed to Wing Chun, have done so as regards the watered down/fused/made up/standardized/commercial variety.
As a result many of them have gone on to find more fighting and self defense relevance in MMA, kickboxing and so on. These systems are less profound, but more time efficient in giving one fighting abilities in the short term, than Wing Chun and most other kung fu styles.
Eventually this type of martial "evolution" results in these cross training or ex-"Wing Chun" practioners turning around and badmouthing an art that they themselves have
never really studied.
Then there is the trickle down effect of others who have never even tried to practiced Wing Chun or Kung fu in general, jumping on the bandwagon of bad mouthing this style. They probably think that if "Wing Chun" practitioners are criticizing this art, then what they say must be true. LOL
It is a sad phenomenon, but this same situation holds true with other kung fu styles as well.
So again, I would avoid schools that spar from early on. Also, be vary of "sifus" who use the hard sell approach, which may include telling you about their school's sports competition medals. Be patient and have a look at quite a few schools.
I sincerely wish you the best of luck.
