Maybe we're disagreeing about what "local" or maybe "realism" means. I
think it means that at the creation of the two photons their
polarizations are fixed (realism) at the same direction, which varies
randomly from pair to pair (non-deterministic), and they interact at the
detectors indpendently (local). Those conditions imply Bell's
inequality. Right?
I don't think OC theories are local. At each detector the collapse is
random, but not the photons don't share the*same* random value.

*The violation of Bell's Inequality does not rule out Pilot Wave
Theory because it is deterministic and realistic but not local. The
violation of Bell's Inequality does not rule outMany Worlds because
it's local and deterministic but not realistic. You can't have all
three, _at least_ one's got to go; I think it's realism but I could be
wrong.*
