Need someone to swipe from. Jaquandor posed a similar, and more expanded query. Mine is more reductivist:
Do you boycott an artist (musician, actor, writer) because you find that person's politics abhorrent - racist, a birther, Holocaust denier? This assumes that the work itself is not abhorrent. Actually remember going to see The Green Berets, starring John Wayne and David Janssen in the day, even though I wasn't a big Wayne fan. Additionally, I knew I'd hate the politics of the film, and I did, but I found it instructive to have seen it. But, no, I see movies by Gary Sinese. I listen to Wagner. I don't buy Ted Nugent music, but then I NEVER bought Ted Nugent music.
Do you support an artist who is the subject of a boycott or other negative action? Heck, yeah. When Natalie Maines of the Dixie Chicks spoke the truth about George W. Bush in March 2003, just before the US invasion of Iraq, and took a lot of heat, immediately, I ran out to the local Rite Aid and bought the Dixie Chicks' then-current album. Likewise, when Linda Ronstadt said something complimentary about Michael Moore and subsequently had some difficulties, I ended up buying her box set from Amazon. This is not that I might not have purchased them eventually anyway, but certainly the events specifically prompted the purchases.
