In a scrupulously politically correct age, it's not offensive to organize a "Kill the police!" demo or to preach that the government invented Aids in order to perpetrate an African-American genocide. You can pull that stuff and still be part of respectable society, hanging out with presidential candidates and whatnot. What's grotesquely offensive is the chap who's insensitive enough to point out such statements and associations. So the North Carolina Republicans are denounced as "racists" for being so unenlightened as to bring up the subject of the neo-segregationist hater Rev Wright.
