Re: When someone tells you that the have a black belt in karate...do you laugh?
from my perspective:
karate alone is clearly not the best martial art to go in a full contact fight vs another martial art.
you gotta take the goods out of it and mix it up with something else.
best example is GSP, Kyokushin BB. He has a great discipline, great mentality and is very respectful, fighting wise he uses mostly the kicks from his karate background (axe kick, spinning back kick.) Otherwise he'll rely on his boxing, wrestling and BJJ.
