That's not what happened: she questioned his parenting because he's a freakshow constantly out there showing he is, indeed, someone it would be a horsefeathering nightmare to have as a parent. His entire persona revolves around him crowing about him being the dad of these kids, so, yeah, let's not suddenly get all high and mighty and act like his role as a parent is off limits. If he had an issue with what she said, he could have responded to what she said, but instead he just decided to be a sexist dick on national TV and didn't address the parenting thing at all. Which, by the way, just furthers the case that he's a terrible parent. This idea that talking about someone as a parent is somehow "stepping over the line" is nonsense. Nothing about this guy is off limits because of how HE has put himself out there.
