Query: Um... Credentials lacking

I would not write a book that deals with physics as I am not a physicist.I would not write a book about catahoula leopard dogs as I've never actually seen one.I would not write a book about how to be a Godly single woman since I'm married with four kids.I would not purposefully read a book about married life by a woman who has never been married- even if she bases her information on the bible. Because I could skip her book and read the bible.Does it bother ANYONE that the woman spouting off marital advice has NEVER BEEN MARRIED?
