Parents can counter a worldview without devaluing the other parent

Evidence

This doesn’t mean that you can’t take a stand and represent different positions. But do so in a way that relates to factual aspects and does not slip into emotional devaluation: “Your mother believes that angels exist and that you can put the magical power of these angels into drops of water. I do not believe that angels exist. And if they do, I don’t believe their powers are in this water. I think this is something that people wish for. We’d all like to be able to do magic.” — Holm Gero Hümmler, Ulrike Schiesser, Fact and Prejudice, 502
