"Well I'm not prejudiced, but..."
Reasonable people can and do disagree on whether certain comments or actions are racist or sexist, but only some kind of complete dope would deny that certain things are explicitly racist or sexist. So if you are a conservative who does not think of yourself as a racist, who is appalled by the recent hijinks of the racist shitheads at F0x News thinks, you really have to ask yourself why you are associating with the some of your fellow Republican and Conservative travellers - and these are the official functions and elected politicians the parties have some control over, let's not even get started on the bloggers and loose-cannon pundits.
Take a look at the comments on this story for an example of what I'm talking about. I'm sure many of the people here --I'm looking at you Diane72, Superpants and Peapod-- would blithely tell you that they don't have a prejudiced bone in their body, but that they know for a fact that (insert ridiculous racist claim here).
