That is the really issue, isn't it? There can and will always be someone offended by virtually everthing. So if "offensiveness" is the standard, then arbiters are required; someone to rule for the crass masses what is acceptable and what is not. Invariably, only that approved by the Left is correct, and that is soul of the plan of PC: Shut down and silence anything that does not conform to the "top-down, iron-fisted" rule of the Left.
