I understand your point about the POVs. In light of that, here’s what bothers me about saying “normality is weird”.
If we look at a quantum-mechanical system from the classical POV, we notice that no classical laws (even classical-style laws we don’t know yet) can explain its behavior. So it looks weird to us. That’s fine.
If we look at a classical system from the quantum POV, we can’t calculate its behavior on the quantum level, it’s too complex. But if we could—and in principle the laws of physics tell us how to do it—then we expect to predict its behavior correctly. So why should it seem weird?
The two situations aren’t symmetrical. We used to believe in classical mechanics, and then we discovered quantum phenomena, and we saw that they were weird. This was because the laws of physics we used were wrong! Now that we use the right ones (hopefully), nothing should look weird anymore, including “classical” systems.
It’s true that QM is at best incomplete, and we can’t yet use it correctly in some relativistic situations. So those situations still look weird from a QM POV. But this doesn’t apply to our normal lives.
