A black man walks into a bar, an iron prison bar.
Oh my that doesn't sound funny to me. Do you think those kinds of black jokes are funny?
People need to be educated to bring out their forbidden thoughts on race.
Some thoughts are forbidden because they can be mean, nobody wants to be thought of as a criminal just based on your race. You would be hurt if people assumed you were a criminal just based on the color of your skin.
Nobody is going to offend me about my race.
Given the right insult you would be offended about your race at some point, and making these jokes would be just that point for many black people. You insinuating that all blacks are thieves and criminals is quite misguided and you should question where these false ideas came from.
