I think he's pretty well stating it, and I think he's pretty well right. (I'd have also agreed with your point-of-view 3 years ago before my first was born.) It's not worth much arguing about, because as a non-parent you'll have other compensating "benefits", but it's hard for me to imagine how much my own world view and views on selfless love changed with the birth of my first (and to a lesser extent, my second).

FTR, I didn't downvote.
