Comedians that use a racial basis for there jokes are often seen as highly offensive, and it is this type of comedian that has received the most criticism over recent years. Bernard Manning, Jim Davidson, and Roy Chubby Brown are at the forefront in this type of stand up comedy.
As a person who is deemed an ethnic minority, I personally find many of their jokes extremely offensive. What I find most offensive about racist comedians, is their willingness to re-enforce stereo types that are inflamortary and not true.
i just believe nasty comedians are a waste of time
