The way this is presented, those objecting had a clear standard that I think is (on some level) reasonable: they refuse to fight in a war involving the death of civilians. Now, I think that's a bit naive, because all war involves the death of civilians, but it seems a clear place to draw the line.
It's particularly important to me that the rights of people to refuse to participate in a war for their own reasons, whether religious or not, whether outside observers consider them to be rational or not, be protected.
This was hardly a mass protest; can't see why it was a newsworthy item. But I'm personally glad to see it.
