Touché.
Sorry about the replies earlier, I wasn’t in the best mood and I can only look back in embarrassment. You have your convictions and I have mine, and it’ll take a lot more than a comment thread to change our respective courses. The least we can do is be civil, and I failed that standard with my juvenile first reply. I should have just said that I think that the concept of “unjust” is somewhat relative and left it at that.
