So Kurt Busiek brought up a topic on Twitter: he read an article positing that authors should keep their political opinions to themselves, especially on social media. Because it could mean losing sales. Which he thinks is bull. He doesn't think writers - and other creative types - should fear their audience.
He has a point. I personally prefer following writers like Busiek (or Mark Waid) who aren't afraid to be themselves. I've seen so many other writers on social media who just go on and on about their work or writing. And that's ALL they talk about. Nothing about the latest news, or movie or TV show, or a book they're reading. Just a constant barrage of "BUY MY BOOK!"
As for losing an audience, I feel like it'd be a small drop in the bucket compared to the people who will still buy their work. For example, I've mentioned before that I don't want to support Orson Scott Card not just because of his opinion on the LGBT community, but that he's on a committee actively fighting legalized same-sex marriage. Unlike some others, though, I don't go out of my way to attack him or make him afraid to continue his work or say his opinions. I just don't support his work. There are plenty of other books out there that it's no skin off my back. I'd rather spend my time catching up on Mickey Spillane, Jim Butcher, Terry Pratchett, and other great writers.
On the other hand, I still enjoy Tom Cruise's work despite that he's the face of Scientology. He's a great actor, and yet there's that ugliness of what Scientology is and the many stories told by people that escaped from that. But I also don't know how much of that he has a personal hand in or how much he's just a spokesperson or front man.
The only time I can think of a writer who might have lost his audience because of his political opinions is Frank Miller. His early work with Batman and Daredevil are to this day still praised by most. But in his later work, like 300 and Holy Terror, his political opinions encroached more and more into it. He's obviously still a successful writer/artist, but I don't think it compares to his heyday. Of course, unlike OSC, his political views greatly inform his work. From what I understand, OSC's homophobia or other views don't inform his work.
Then again, Miller also said he voted for Hilary, so I'm really not sure.
