Loathe though I am to give you more of an excuse for your self congratulatory masturbation; you are projecting an extremely attenuated perspective of gong fu. You haven't even mentioned shuai jiao while also ignoring the existence of the wide range of northern styles with the exception of bagua, you make offhand mention of mantis but have you ever really seen any actual mantis?
He also totally ignored other systems like CLF who is in the rings these days. I think he has selective vision.
Typical story I guess - you got grafted for years by some wing chun school and now express your bitter resentment by projecting your narrowly subjective experience onto everything. All this self obsessed bravado reeks of insecurity and the only new insight I have gained from this thread is your woefully regrettable body art and interior decorating decisions.
Personally, i think you hit it on the money. he's bitter about his experience with CMA. And, even if you showed him something decent, its a GIVEN that he's gonna shoot it down with a typical shot of "Either way, this in no way represents the high level of pro MMA. No way!" I think its safe to say he'd give the same response event if it was PRO MMA he's checking out. And, i'm not even trying to disrespect the guy.....it's just how he comes off
