I believe the parent was relating what was believed at the time, not what is common knowledge today. I'm not sure he's pushing his views on anyone, but more relating what the view at the time was. Careful of cognitive dissonance here - what once once was isn't necessarily what is today.
I apologize if it sounded like I was pushing my opinion on anyone. It wasn't my intent. I'm only here to learn, so I genuinely hope people will correct me when I'm wrong.
