"My whole incest thing? You're the one who brought that line of argument to the table"
Nope. That was a straw man you threw up between yourself and the argument I actually posted. Nothing I said implied anything about incest, except when I was pointing out that your introduction of the matter was a straw man.
"you're preaching, not reasoning."
Definitions:
Preaching: making reasoned arguments that incorporate moral concepts.
Reasoning: doing whatever is necessary to arrive at the desired conclusion, which requires excluding moral concepts.
Most of us define those terms differently.
"I think we've covered all the ground there is to cover here"
Actually, you haven't even taken your first baby step toward thinking this issue through. You wasted time on your "incest" straw man, but haven't even acknowledged the major arguments presented against you.
"Frankly, you're not worth my time."
No good deed goes unpunished, I guess. Oh, well, more people are persuaded by experience than by argument, so there's always the chance that you will find yourself 20 years from now trying to explain my position to someone who, like you now, cannot bear to face the reality of the situation.
Again, you were the one who attempted to use my nieces as a rhetorical device in this dicussion---"would you care to see your nieces in Playboy magazine?." No, I would not. I would not care to see my nieces in Playboy magazine. I would not care to see any of my relatives in a sexual situation, quite frankly.
Explain to me how I threw up a straw man by responding in this manner.
