Obviously I'll have to come to terms with the fact that "people in the world" have different priorities to mine regarding ethics; that doesn't change the fact that I believe certain things to be wrong and that (independently) I believe people should be held accountable for actions, even if just following orders (which was the original argument I was responding to).
Working for the NSA isn't a human rights issue, another reason that the gay marriage thing is a straw man. I'm not claiming someone shouldn't have the right to work for them, I'm just saying if they're instructed to do "wrong things" that those things are still "wrong" even if you're only doing them for your boss. (for whatever values of "wrong" -- hence your point about ethics being individual)
