Whats up with old schoolers using this for a ego boost?

why do traditional martial artist think what ever style they do is so amazing and unstoppable.take tae kwon do black belts since every one is one.why do they answer every question by putting down other fighting styles like mma.which is martial arts made from all martial arts only with the infective moves removed.which is how every martial arts started.do you think they honestly think this high of them self's are they jealous they missed the buss to the future and their gold pot is running out of gold coins.
