They hurt blacks because they remind us of what we already know, have learned, and live with every day. There is humor there but also hurt and bitterness, given I was a three degree professional with a major corporation in one case and a four degree university instructor in the other case. Tom Joyners' show, Urban Humor, is a continuation of that genre, funny and bitter at the same time, because it gives blacks and nonblacks a chance to view and in some cases to laugh at foolish racist attitudes and stereotypes, new and old, held by held by both blacks and non-blacks. Much of the show is like cartoons, which we know are not intended for children, which make important points. There are some parts that are distasteful, admittedly, but no more so that Rush Limbaugh or Don Imus excoriating the President or his wife or for that matter, Jay Leno.
Racism does exist in our country.
It should not. Joyners' humor is very painful at times, if humor can be derived from one's painful condition. I don't know about you, dear reader, but there are few places I have been in the U.S. or the world where there was not someone of color. I remember looking a Brazilian magazine with a dear friend and noticing the same thing. He was insulted when I pointed this out to him, given the large number of people of color in Brazil, other than Pele.
