I agree right and wrong is good when it's fundamental enough to bet it'll last their lifetime and isn't simple preaching. But also complex human emotions and interactions are useful and interesting to them. The politics I'm complaining about is far more specific than that and I don't think 3-5 year olds either need it or can understand it - like environmental pollution, punishing capitalists, which ancient battle some holiday commemorates, life story of a specific politician, endangered species, cultural headgear, etc.

My kid seems to prefer choosing classic stories over the piles of modern books we also have.
