Just keep pointing out the flawed logic each time it crops up. Set her a challenge: research and argue from the opposite perspective, as an exercise, and you’ll do the same. Tell her that you used to find it hard to stomach opposing viewpoints when you were her age, but that to listen is an important social skill.
I’m a secondary school teacher and I always ask my form to look at things from different perspectives, and I challenge this ideology often, because teenagers only tend to hear one side of it. Obviously I don’t tell them what to think (or what I think), but I remind them of the importance of evidence-based debate and considering opposing viewpoints. We also have no ‘no debate’ or hurt feelings, we agree that if we’re going to debate something, then we remain respectful.
