I know this is not a popular view, but I am not convinced of the validity of
such experiments. One proponent of the realist opinion, who has better
arguments than I, is Caroline Thompson:

I admit I'm not too familiar with these concepts or terms. I'll try to
understand them a little better.
In the mean time, my main objection to non-local phenomena is, once again,
our inability to formally implement it.
Challenge: write a set of non-local equations or a non-local computer
program that isn't implemented locally.
For example:
It would be easy enough to program a virtual reality simulation to exhibit
seemingly non-local behaviors. We could even do something extremely
macroscopic like joining the motion of two pool balls firmly together - so
that whenever one was moved, the other moved also - seemingly
instantaneously.
>From all indications, to the inhabitants of our virtual reality, their world
is non-local.
But they should know better. They must realize that even though they may
see non-local phenomena happening around them, they could always be fooled
by SOME local communication happening behind the scenes.
And so... our virtual reality simulation, being run on a conventional
computer, literally has HIDDEN VARIABLES that the inhabitants don't see, but
we can.
It seems a popular fallacy to say that Bell "proved" that no local theory
can account for the experiments. But this is not true at all. From what I
can tell, Bell only showed that Quantum Mechanics, as it is formulated, is
non-local. But this is a far cry from showing it in the "real world".
If we're intent on looking for magic, we needn't go so far as quantum
mechanics. For that matter, we could say that Newton "proved" that gravity
is a non-local phenomenon. And, to some extent, we would be correct.
Experiments show that gravity travels instantaneously from the Earth to the
Sun... and all the bodies of the cosmos simultaneously.
But we know better...
We know that SOMETHING must carry the information from one place to
another - even if it appears to be happening instantaneously *from our point
of view*.
