No I don't think it's necessarily the parents fault for religious intolerance. I think it's more people not being educated enough though the way one is raised also has to do with it. I remember growing up in a small town that was mostly protestant Christian while I was brought up more the catholic way. I hated that small town so much that I was glad when after high school I moved to the city and now I never want to live in a small town again. I like the diversity of the city here. So many different people with different beliefs that you are more likely to find people who share similar beliefs while also getting to know others point of view.
