So, experimental violations of inequalities based on Bell locality, while they do rule out Bell local theories, don't imply nonlocality or necessarily rule out [STRIKE]local[/STRIKE] realism.
imply nonlocality, but does not rule out realism.

...the Bell theorem has demonstrably nothing to do with the 'realism' as defined
by these authors
Leggett, Zeilinger, Gröblacher and that, as a consequence, their conclusions about the foundational significance of the Bell theorem are unjustified...
...the role of Bell’s theorem is not to set constraints on how ‘realist’ we are allowed to be about quantum systems...

...In recent years the violation of Bell's inequality has often been interpreted as
either a failure of locality or of realism (or of both). The problem with such a
claim is that it is not clear what realism in this context should mean. Sometimes
realism is dened as the hypothesis that every physical quantity always has a
value and that measurements merely reveal these predetermined values. That
is, realism is identied with determinism. But if so, then, rst, why should
one use the word local realism instead of local determinism? And second, Bell's
inequality can be stated and proven without any assumption about determinism.
Consequently, determinism is not the issue......
...In conclusion, the claim that the observation of a violation of a Bell inequality
leads to an alleged alternative between nonlocality and non-realism....However, it is not specifc to Bell inequalities......Hence, all violations of Bell's inequality should be interpreted as a demonstration of nonlocality...

...There is hardly a result that is more widely misunderstood in the scientific
community than Bell’s theorem...
...To summarize, what can one conclude from the violation of Leggett’s
inequality ? ....That doesn’t tell us anything about determinism or any type of philosophical realism.

...What really matters is the fact that the derivation of Bell’s inequality in no way whatsoever needs an assumption of realism...
....This being the situation we must conclude that in no way whatsoever Bell’s
inequality has something to do with realism. It simply identifies in a straightforward
and lucid way that what quantum phenomena impose to us is to accept the
unescapable fact that natural processes involving entangled states of composite
and far-away systems turn out to be unavoidably non-local...
....or by those who derive from experimental results inspired by not strictly convincing theoretical models unjustified conclusions concerning such an important issue as the one of the reality of the world around us.......
