The problem of course is that a great deal of politically incorrect humor is extremely funny. The very best joke I know falls into that category, and I can't relate it here.
@lauren Politically Incorrect is ov course a creation of right wing tanks in the 90s-2000 to make being racist appear cool. Broadway show, movie, TV show with the title followed. For me the rule of thumb is Molly Ivins': weapon of powerless against the powerful. Otherwise, cruel and vulgar.
