Uhhhhh, damn dude. Words kinda fail me here. As a male Marine, with several years practice in BJJ, I find your comment either offensive, or just plain stupid. I've had my ass kicked many, many times by female Marines. I had several MCMAP (Marine Corps Martial Art Program) trainers who were female. For that job, you are required to win at full contact hand to hand combat with people bigger and stronger than you. Your comment is sexist for one, and ignorant for another. I have a few female friends who've read your comment, and would like to have a friendly roll with you, if you are game.
