(3) Suppose I really like AWEAJ, and suppose they support a national socialist organization with their own money. But furthermore, suppose this organization has been known to engage in illegal and immoral acts, such as violence against "undesirables". Let's suppose for the sake of discussion that AWEAJ doesn't actually engage in such acts; they just give the organization money. Do I have a duty to refrain from giving AWEAJ my financial support? I'm not sure. The answer would perhaps seem to be 'Yes', but might there be good reason to doubt that?
Let's apply the principle about duties that I proposed to the cases under consideration. If I have a duty to refrain from giving financial support to AWEAJ on the grounds that it would constitute indirect financial support for their cause, then anybody else who has the choice to refrain from financially supporting AWEAJ and whose financial support would result in indirect financial support for their cause has a duty to refrain from financially supporting AWEAJ. But buying somebody's album is not the only way to give someone financial support. Employing somebody at a company is also a way to give someone financial support. Notice that employers have a choice whether or not to hire somebody, and notice also that their financial support is also potential financial support for whatever cause the employee is involved in. This would mean that if I have a duty not to give financial support to the members of AWEAJ by not buying their albums, then employers also have a duty not to give financial support to members of AWEAJ by not hiring them. We can multiply examples by simply thinking about more forms of financial support. What is the consequence of all this? It would seem to be that, in a society of people who were all aware of AWEAJ's allegiances, if I have a duty to refrain from financially supporting AWEAJ, then a very large number of other people do as well, and if everybody follows their duty, then AWEAJ would have almost no means of sustenance. Is this an acceptable consequence? It seems pretty insane to me. It certainly wouldn't be acceptable in scenario (1), but what about the other two scenarios?
I realize that what I'm saying might not make a whole lot of sense to any of you, but if you follow what I'm getting at, do you agree with my reasoning here? If not, where have I gone wrong? Is the duty principle wrong? Is the consequence I draw from its application wrong? Am I a ridiculous person?
Do any of you think that we have a duty not to financially support bands like AWEAJ? If so, then in which of my three scenarios would we have such a duty? If you don't think we ever have any such duty, why do you think that?
Oh and I realize that some people simply refrain from financially supporting NS-affiliated bands just because they feel "icky" about possibly financially supporting a cause they don't like without actually thinking that other people are obligated to refrain as well. However, I should say that if you genuinely think that financially supporting a certain cause is morally wrong then there's no reason to think that other people are justified in not refraining.
Sorry for the long post. I'm sure I'll get a few tl;dr's.
