Hmm! I spend an awful lot of time teaching people to punch. In my Krav classes many of them have been boxers. The fact that now they are learning to punch bare hand changes things a lot and every one I have had so far has been punching with a tense arm.Craptastic striking equals I don't have to bother because eye gouges gives me the street edge over a punch.
I have no problem with the striking aspect of martial arts.
