Nonetheless, Limbaugh broke out the racial shoehorn to reinforce whatever point he was trying to make, and in the process insulted Native Americans: "If we want to talk about richness of experience, there's a group of people that were here before we got here, gang: the Indians, the Native Americans, the chiefs, the redskins. I don't see any of them being put up on the courts. Talk about a richness of experience--hell, these clowns beat Custer. They have cred. You don't see them being put up, do you?"
Note that even though Limbaugh is nominally sticking up for Indians, he's really insulting them. He calls them "chiefs" and "redskins." He talks about their defeating Custer as if "they" were all involved in that and "they" haven't done anything noteworthy since.
Most important, he calls them "clowns," which in his mind is similar to "chiefs" and "redskins." No doubt he's gotten all his "information" about Indians from dancing Indian mascots.
It's funny that the defenders of the word "redskin" don't understand what many Americans think about it. To these Americans, a "redskin" is a "clown"--i.e., a primitive savage in gaudy feathers and warpaint who did nothing but kill Custer in battle. And after being defeated by the US Army, refused to work, received welfare, got drunk, and died out.
