We model good decisions based on what people we respect tell us all the time. Maybe Taylor Swift isn’t the ideal role model, but she’s certainly not the worst one I can think of.
Politics is not something most normal people think a lot about or have coherent views about. I don’t think it’s all that crazy to think that an important role model could work as a heuristic for figuring out what their own values are.
