I don't really get the sad pessimistic spin people such as the author put on the idea that we have to realize our partner has problems and will piss us off. Maybe it's because I never bought in to the whole "Mr./Mrs. Right" romantic mumbo jumbo bit but that just seem incredibly obvious. I know my BF's issues and he knows mine because we are here to help each other grow. I know that if we have kids he will be able to excel in ways that I can't and they'll get more out of it that way. That is stuff to get excited about, not pessimistic. Personal growth is always exciting and getting to share that journey is great. It also doesn't hurt that he cleans a lot.
something something ad-hominems don't really prove a point something something something. It is true though. Also his wiki article mentions his work receives mixed reviews: positive reviews for bringing philosophy to a wider audience, and negative for pompously restating the obvious and lack of focus. Everyone who wants to get philosophy to a wider audience gets the same criticisms, probably because only someone searching for the same revelation the author was will find it in his work.
His background gives some insight into why he thinks the way he does. If the article was "Why I will marry the wrong person" his background would be completely relevant. But he didn't so whether what he wrote applies to the world or its just crap is what is relevant.
