If you took two identical twin brothers, on learned muay thai, and the other spent an equal amount of time learning kung fu. The kung fu man would get his face kicked in. It's as simple as that.
LOL I love it when people talk like their word is absolute fact. It's so ridiculous it's actually amusing! I wonder if this guy has actually ever taken two identical twin brothers, got one to learn from a proper Muay Thai teacher and the other to learn from a genuine Kungfu Master (not one of these bogus dancing phoneys), watched them both practice the same amount of time and then asked them to fight each other. I'd be interested to see the results but I wouldn't be so arrogant and presumptious to assume that the Kungfu practitioner wouldn't stand a chance.
