No you don't have to like them. I mean there's always gonna be sooome aspect of someone that you don't agree with. But I get it, I suppose you're referring about something like what Mel Gibson did, or if you're talking about jerks and egotisical person, maybe someone like Kanye or whatever, if you were to base what you consume solely on the person and not the quality of the work then you're really limiting yourself. But it's not bad, I just think personally it'd be too limiting. Personally, I like to separate the art from the artist...most of the times.
