Societal norms play a role in our choices whether we are capable of seeing this or not. I'm not making this up (what would be in it for me to make such a thing up?) If we were raised in a society where nobody got married, we wouldn't either. If we were raised in a society where women covered up from head to toe, we would to. It's not about assigning blame or not taking personal responsibility for our own choices it just how things work. My friend who is Christian honestly believes that if she were raised in a Muslim country with Muslim parents she'd still be a Christian because she makes her own choices. Not true or logical but people can believe what they like.
