I mean, lots of people have different views. It’s ludicrous to expect other people to have the same views and opinions.
True, of course, but a person’s moral and political opinions are legitimately subject to moral judgment themselves, and can inevitably influence one’s view of the person’s character. I’m sure we can all think of opinions which we find reprehensible (according to our own subjective standards), and there’s a spectrum of lesser negative views before we get to that extreme. I think that my responses to an artist’s work are mainly determined by the work in itself, but there is at least a certain extent to which the process is an interaction with the artist (or one’s conception of them), and, as a result, negative views of the artist can have an adverse impact on the experience of their work.
