In my view you're putting your perspective as if every street corner was filled with bloody thirsty streetfighters and MMA practitioners. MMA is NOT SD.

Wrong then im afraid.
I can put MMA type drills and sparring in perspective and know full well what it is and what it is not.How could I not after bleeting on about putting TKD into perspective.
I just find it sensible,more fun and challenging to train with a highly skilled opponent in mind.
I still train in TKD and actualy find more in it now making personaly adaptions and applications.
I dont feel you see how MMA/NHB type drills can cross over to SD or what type of drills go on or how they can be created to fit many, many situations.
