While I don't agree with the author exactly, I do admire someone sticking to their guns (no pun intended). Like Oscar Wild said, "Morality, like art requires drawing a line somewhere".

One of my favorite 80's movies was Real Genius with Val Kilmer. He accidentally helps develop a weapon and then goes to extreme measures to prevent its use. For some people creating weapons is a line they wont cross and that's not a bad thing.
