Without having read the book or arguing for one side or the other, I have to point out that you aren't attempting to meet with the argument or even attack the premises. Instead, you're looking at the conclusion and declaring that, in effect, it is immoral to even argue for that position. This is dogmatism; this is wrong; this is antithetical to sound and rational behavior (to be clear, "this" is your argument, not his!). In short, you /might/ even say that what you've just done is... evil.
