In the discussion under his confused musings about the CHSH inequality, a volatile anti-quantum zealot had serious problems with the following important wisdom:
All differences between classical physics and quantum physics are consequences of the uncertainty principle i.e. of the nonzero commutators between observables.Well, the statement above is true and important. The misunderstanding of this statement – often arrogantly masked as a different opinion, one that may be presented assertively – may be considered one of the defining characteristics of the anti-quantum zealots.
The anti-quantum zealots are inventing lots of "additional" differences between classical and quantum physics – such as the purported "extra nonlocality" inherent in quantum mechanics, or some completely new "entanglement" that is something totally different than anything we know in classical physics, or other things. Except that all these purported additional differences are non-existent.
