It's only the second rate musos who have to put down others (for the sake of their own egos!) - often they will put down someone they THINK is bad, but the person may just be foxing to test them - if they don't know their face...

remember that the martial artist who has passed several dans of black belts in some styles wears a WHITE belt - because they wish to FORGET everything and start with the mnd of a beginner... :-)
