"Eat the fish, spit out the bones" is a good motto in learning from others.  You may not agree with everything, but you certainly can find something to take-away.

I was impressed by the willingness of this person to stomach the music to get to the teaching.  The style may not have been his personal taste, but he wasn’t going to let that skew his judgment so much so that he missed the meat.

Rock on mister orange-ear-plug-go-everywhere-in-a-suit-man.  Rock on!
