I can completely understand why you would think that I meant something different. The topic lent itself to something of that direction.
I completely understand you being confident of your moral standpoint. All I was ever saying was that 15-17 year old kids don't have a moral compass. If they do, it's located down south and pointed upward, if you catch my drift.
Would I want to be the mother's son...hell no. Hell, I'm sure that my GF's parents don't approve of her dating someone as old as I am.
I guess an easier way to put it is like this; it's easy for us to make value judgments because we have the benefit of hindsight and objectivity. Additionally, I don't know how old you are, but your logical progression, syntax, and manner of speaking suggest someone of advanced education, so I'll guess somewhere in the mid 20's. If I'm wrong, I'm sorry.
That being said, we're not 16 (I think), so we're thinking with more than our penis'. I did that when I was 18. Probably not much more advanced than I was at 16.
