I don't think it's fair of you to imply what he did not imply. Despite all the 'cultural-sensitivity' and what not, there are some lines that have to be drawn and stated bluntly and unapologetically. In that respect, I could not have said it better than the parent comment, and 100% agree with below statement:
" Any 36 year-old man, from any culture that has ever existed, that finds it acceptable to marry a 9-12 year old and then start raping her when she's 13 is a piece of shit. Any culture or individual that condones such behavior shouldn't exist anymore."
Actually there are a lot of eras that had a very low life expectancy in early times [1]. Giving birth at an age earlier than what our society finds acceptable would have been normal, if not the responsible thing to do, for those eras. Otherwise the parents would be living an unprepared 5 year old alone in the world.
I don't really subscribe to the misinformed view that one has to be perfect in order to recognize a flaw. I criticize my own culture as much as any other, perhaps more.
