I was specifically referring to the value of the actor as a contributor to a society's culture.The value of any act lies in the positive effects it has for the actor. Why would you imagine that value to be less because people value other things more? For example, I value my life more than drawing Mohammed and putting my name to the drawing publically. Are you suggesting that if I can be cowed (by credible threats of violence) out of drawing Mohammed that means it's wrong to draw Mohammed?
An actor who is easily cowed offers little value to society; if an museum bows too readily to the demands of complainants then the director ought to be fired and replaced with someone with more backbone, lest the museum become irrelevant.
Similarly, if an author were to change their work to please anyone with a poorly-argued complaint about that, then their value as a writer and the value of their work would be greatly diminished. Who would give a damn about Rowling if she revised the Harry Potter series to please fundamentalist Christians?
If it takes credible death threats to stop you from publishing a work, you are hardly comparable to actors who are cowed by far, far lesser dangers.
You've previously called me a bully based on nothing but extremely mild words on a forum; you use the term too readily.CA mythicists are bullies. It's true that each person has to decide for herself whether doing something is worth the bullying. But the problem is the bullies, not the marginal value of whatever they're bullying you over.
In terms of marginal value, my opinion is that some institutions such as the museum are doing a poor job of judging the marginal value of their choices. They overestimate the costs of their actions, and underestimate the value of showing the proverbial finger to obnoxious, incoherent protesters.
