The YouTube video, Bell's Theorem: The Quantum Venn Diagram Paradox, was trending as popular. It is pretty good, but exaggerates the importance of Bell's theorem.
The basic sleight-of-hand is to define "realism" as assuming that light consists of deterministic particles. That is, not only does light consist of particles, but each particle has a state that pre-determines any experiment that you do. The pre-determination is usually done with hidden variables.
Bell's theorem then implies that we must reject either locality or realism. It sounds very profound when you say it that way, but only because "realism" is defined in such a funny way. Of course light is not just deterministic particles. Light exhibits wave properties. Non-commuting observables like polarization cannot be simultaneously determined. That has been understood for about 90 years.
There is no need to reject locality. Just reject "realism", which means rejecting the stupid hidden variables. That's all.
