I am somewhat of a purist. I will study Shiua Chiao first before I give in to this trend of BJJ. Unless of course its a womens class, then I am all for it.
Somehow being in kissing proximity of a sweaty guy named Bob and "mounting" him just does not sound like MA to me. More like gay porn. With all the grunting and red faced efforts. No thanks.
Doesn't sound macho on the streets either. Can you imagine threatening a guy. "I gonna mount you and beat you to a pulp" In some neighborhoods that's a romantic evening for a guy and his life partner.
