You don't mind them sonically blurring out the offending words. Like that Maroon 5/Christina Aguilera song where he sings the refrain "....I don't give a sh1t" and the word is blatantly cut.
Rather it's the actual altering of the lyric that is actually ridiculous. It snuffs out the original content and it's censorship like that which irks people. However, you get to listen to it with it's original content any time you wish and if radio stations/DJ's who have control of content decide to censor songs from their play lists then just accept it as their prerogative.
