ACE, it ties into the death penalty where personal morals are concerned, so it's very much on topic. When someone chooses to argue with you, obviously the more you know about 'why' they think what they do, the better prepared you are to answer them and assert your own, differing viewpoint.
I believe, as I do with most people, that yours and Sundin's anit-death penalty position, is partially based on some religious or spiritual underpinnings. And I still do. People who state they are agnostic come from religious backgrounds and still struggle with religious principles, they were taught to believe but now, being older, find themselves having a real hard time with the common sense of it all. That pretty much explains you.
I stated you were religious or at the very least spiritual, you said I was wrong about that.. which led me to ask you directly. So while you may not follow or practice any type of organized religion presently, your claim to being agnostic betrays the religious background you're now at the crossroads of explaining with reason, a place where people go,... "Well, I'm really not sure if there's a god, I mean it doesn't seem possible, but again, I just don't know".. that's what an agnostic is.
So as much as it annoys you, because we don't know each other, I'm gonna go ahead and stick with my assertion that the religious sludge still adhering to the various parts of your brain is partially responsible for your opinion on the death penalty, as in..
'What if there IS a god and I've been running around advocating the murder of people'
Now you wanna try telling me I'm wrong again, feel free, but that honestly is a pointless endeavor because I'm not. There's a reason people think the particular way they do and, depending on the subject, it's often pretty easy to find the solid mathematics behind it..
