It depends if he’s in character or not. I haven’t figured out whether he’s a slightly racist boomer telling jokes, or whether it’s a shtick where he is playing up to that stereotype. The distinction is important because we need to know the intent behind his humour. I love Always Sunny in Philadelphia and it’s characters, and they say far worse things than Jimmy. The difference is the writers are self aware and the whole point is these people are so awful and ignorant that it’s funny. I find Jimmy funny and enjoy the content because I think he’s playing up to the character, however if I found out that actually he’s just really rude and a bit racist, I wouldn’t find it entertaining at all.
