You think we are trying to silence you by telling you that fried chicken jokes are racist?
Criticizing Obamacare is not racist. Wanting smaller government is not racist. Resisting federal influence in the states is not racist. Even wanting intelligent design taught in schools is not racist.
People are not trying to shut you up by calling you a racist. You bring that upon yourself. If you make a fried chicken joke, or a monkey joke, or a watermelon joke, then that makes people think you are racist. But they are not trying to shut you up about states rights or small government, they are trying to shut people up about fried chicken jokes, or in your case telling black people they should not be offended by fried chicken jokes.
If you want to be taken seriously, then you need to acknowledge that people are offended by these things, and not dismiss their offense.
Ideally nobody would be offended by anything. But that does not change the fact that they are offended.
