What irritated Philong was the "roll with JJJ practitioner" thread. Several people, including me, disparaged JJJ habits of gouging deadly pressure points during rolling.
There are certainly vulnerable points on the human body. Philong, if you want to lump the testicles, and kidneys into that, and confirm the obvious, that getting hit in those places hurts, then you win. Pressure points work. I concede the point--getting kicked in the balls hurts. You may commence calling me a little boy.
I'll qualify that concession with this though: testicle kicks, eye gouges and many small joint manipulations (although they do work if you catch them) are low percentage in actual fights. All humans, not just trained fighters, are aware that those points are vulnerable. If you do a football punt style kick even vaguely towards the centerline of an untrained man, he will instinctively put his legs together and turn away to protect his "boys". Similarly, most people, fighters or not, protect their eyes. You can't count on some of the moves that are supposedly t3h d34dl33 in TMAs to end real fight.
However, most of us think of pressure points another way: vulnerable points on the human body attacked with pressure or light striking. One, as mentioned previously, is just beneath the bridge of the nose, another behind the ear, there are certainly more. Those areas hurt when you apply pressure--no doubt. I don't think any of those "kinds" of pressure points produce enough pain to make anyone trained drop a submission or choke.
Lastly--not all TMAs or TMA practitioners suck. There are certainly TMAs that produce good fighters, and TMA schools that train hard, with resistance. No martial art, whether BJJ, JJJ or whatever has a lock on all aspects of combat.
