The thing about the Frank Miller "controversy" is that first of all it has nothing to do with comics and it's being blown way out of proportion. The thing is comic fans, comic sites and comic creators all felt the need to weigh in on this with multiple articles and massive amounts of "tweets." It all lead up to a boycott of his work and basically looked like the downfall of Frank Miller all because of his opinion not being popular. That's right the man responsible for Batman: Year One, The Dark Knight Returns, Sin City, 300 and really google the man to find the rest of his extensive body of work; looked like he was on his way out because comic fans are as fickle as the weather.
Then Mark Millar posted a great response to the "controversy" on his site which you can read here (I don't believe in re-posting someone ones entire article and stealing hits from them). He brings up great points such as the mob mentality of the internet and the bandwagon effect. I'm sure several creators "weighed in" on the "controversy" just because they were approached, not because they had an opinion. Personally, I don't care what his opinion on politics is. As long as his views don't advocate the harm of anyone then I don't care. What baffles me is that comic fans were so willing to turn on this man that's delivered countless stories that are sited as works that changed the medium and yet his personal opinion is what he's judged on. We have professional athletes that have been accused of rape that are still beloved and playing today, but Frank Miller doesn't like a protest and he's blacklisted? And we wonder why Marvel and DC can't get their shit together when their trying to cater their companies to fans that change like the wind.
Here's my take for what it's worth: Good comics are good comics and that's all. Creators of such comics can be right-wing, left-wing or something else altogether and I don't care as long as the story is good. The only time I'll blacklist a creator for their opinion is when they've done something in their personal life that has hurt another person or again advocated the harm of another living human. Not for their opinion, not for their political views, religion, creed or national origin. It's a scary time in our world when comic creators can't even exercise their first amendment right without being crucified by their industry. But hey, what do I know? I'm just a guy that gave Holy Terror a 5 out of 5 because I could see that it was a statement on how American's viewed the Islamic faith after 9/11, rather than a short-sited view from the creator.
P.S. If you're so quick to write Frank off then I better not read anyone talking about The Dark Knight Returns or Batman: Year One when then next movie comes out or the next landmark run on Batman because you don't get to have it both ways.
