I hate spineless people, men or women, who push others around who are at a disadvantage and beat up on those they know are physically weaker (the same thing revolts me with those who take advantage of the elderly or mentall handicapped). The karate guy handled himself perfectly. I think it is a finely justifiable thing that the pimp got laid out with that move, which just reminds me of a pimp's back-of-the-hand bitchslap.
And I'm also sure that he and probably the whores were high on something or other.... His movements were not just erratic, they were dulled AND erratic... A great contrast to the karate masters quick and solid blow.
