That is also my opinion, my strong opinion. It seems very contrived
that the initial conditions of the universe were set up in exactly the
right way for it to fool us forever. I am reminded of Einstein who
said "/Nature is subtle but not malicious/".

Local hidden variables are ruled out if nature is realistic.

Yes, Bell's inequality is a theorem that can be derived using just
high school algebra starting from the assumptions that things are
local and things are realistic.

If that were true then the MWI and all other quantum interpretations
must be dead wrong because exparament has proven beyond doubt that
Bell's inequality is WRONG.
You mean Bell's inequality is violated by quantum entanglements...which
means at least one of its premises is not true. The obvious one is
locality. MW are a non-local as you can get...which world you are in is
a non-local variable.
The high school algebra used to derive it is not wrong therefore one
or more of the assumptions it is based on must be wrong. Many Worlds
predicts that Bell's Inequality would fail an experimental test
because Many Worlds does not assume realism.
>///I don't know what you mean by 'realism'. /
If realism is true then things, like the spin of an electron or the
polarization of a photon, exist even when they are not being observed
and they always exist in one and only one definite state.
Then that state is a local variable and would make it impossible to
violate Bell's inequality.
