Perhaps I'm misreading you, but this comes across to me like "if you don't have kids yourself you could not possibly understand". That is, I believe, a thoroughly wrong position to take about most anything in life. Exposure to phenomena like "kids" is rather abundant in most societies. For parents as well as non-parents. Observation and analysis about how those phenomena processes seem to be behave can even sometimes be made more accurate by those not emotionally bound up in the here and now. I believe there is no argumentative authority arising from the fact that one is or is not a parent. To settle what might be an authority issue for you: I don't know about jdietrich, but I have kids and I mostly agree with him.
