Let's say that you're gay (and or a big supporter of equal rights or gay rights if you prefer) and a friend turned you on to old records from Pat Boone.

You fall in love with his music but then one day you find out that he's an enormous, outspoken homophobe.

I don't know how I'd react in this situation but I'd have to think it would taint the music to some extent. It's one thing to be generically Republican and quite another to be a hard-core bigot/racist/homphobe.  ; Or maybe you disagree.
