Real physics is local.

Where are you getting this from?

Every single physical theory that is currently considered fundamental is local, from general relativity to quantum mechanics.

I dislike the wikipedia article on the subject, it gives far to much credence to the fringe notion that maybe there is a way to exploit entanglement to get faster-than-light information transfer.

The quantum nonlocality article is much better, it correctly points out that

it (quantum nonlocality) does not allow for faster-than-light communication, and hence is compatible with special relativity.

Does quantum nonlocality count as not being real physics?

I was unclear, of course it is real physics. By "real" I mean simply something that occurs in reality, which quantum nonlocality certainly does.

Quantum nonlocality - despite being named "nonlocality"- is actually local in a very important sense, just like the rest of physics : information never moves faster than c.

It follows from special relativity.
