Sorry I didn't read the whole thread, maybe somebody mentioned it already - but how about Metallica suing their fans over illegal downloads?.. Sure, they were right, business-wise, but still...
I am bringing this just as an example how, IMO, there should be no problem enjoying the artist's - musician's, painter's, actor's - work even if he/she/they is/are complete a**hole(s). Seriously. Creative people are more likely to be freaks, or worse. They have more temptation to become arrogant...
I take artists like Metallica as a force of nature, really. Admire, without wanting to get too close. I can't say I am a "fan" of theirs, but at the right time, their music sounds to me fantastic, among the biggest sonic joys I have ever experienced. Their collaboration with symphonic orchestra is the only rock/symphonic collaboration that sounds natural to me (well, perhaps Rick Wakeman... but that is much "softer" music). And I have no problem listening to that music even though it is made by people with whom I would not share the same field field for a poop, as they say where I grew up.
