The sort of people who get involved in MMA are, generally speaking, insufferable. The MBF (Macho Bullshit Factor) is off the scale. If you want to learn a martial art, pick one that is utterly impractical; those are the ones that attract the people who are really interested in improving themselves, rather than indulging macho fantasies or winning trophies. Anybody who uses words like "real-world," "modernized," or "combat-oriented" should be avoided. If you want to learn how to fight, join the Marines.
