I accept that some people may find it morally right (or thrilling, fun, whatever) to kill. If he or she acts on it, he brings undeniable pain and suffering to the victim and their family. He takes it upon himself to assert that someone else is not fit to live. Who the hell is he to do that? What makes his moral decision superior to that of his victim?
Nothing makes it superior. I don't even understand what you really mean by that. One decision is only superior to another when we define a framework to work with. The question "who the hell is he to do that?" is a bit like asking, "who the hell is an earthquake to kill several thousands of people?" The earthquake just goes ahead and destroys cities. A murderer goes ahead kills people. They don't have to be anyone special.
People will suffer, and they can't help it. Why should that ever be seen as acceptable? Why should someone who feels it's ok to hurt others actually be in the right in any way? Why should their moral choice be the one that is allowed to win out over the other?
I'm not saying it should be considered acceptable. That's a whole different question. I'd try to stop people from harming others because I don't like needless human suffering. I'd fight so that kind of moral choice isn't allowed to win--not because it's wrong, but because I don't like it. That's what it comes down to: power, influence, politics.
Skeptic must feel strongly about the importance of "honor", so much so that he belittles those whom he doesn't consider manly enough. It's a kind of social pressure. I have no sympathy for that kind of value. In fact, I actively fight against it. I fight against the notion that we are not allowed to be true to ourselves when we are harming no one, the notion that men should be men and women should be women because that's just who they are.
I don't oppose that sorry notion because I'm in the right, whatever that means. I oppose it because I don't want to live in a world dominated by it. It makes me happy that we are winning. Sometimes it feels like there's still a long way to go, but I figure we must be doing something right when I hear people whining about how we are all "brainwashed by radical feminists."
