Bells theorem is wrong. It misrepresents the classical case. Let's review Bells theorem. Bell says that if you measure light intensity after a series of polarizers its resulting intensity should follow a cosine distribution when plotted against the angle of relative polarization angle. Bell is correct when he says this, but when the classical case is presented it's claimed that it should be a linear distribution. This was never the case. The intensity classicaly would follow cosine too. This law of polarizers predates bell by 150 years. His ignorance of it leads him to wrongly conclude classic physics is wrong. Here is a link

Check out the discussion at 4:20. They completely misunderstand the classical case. This error can be found in all discussions about the necessity of a quantum explanation.

The op picture is the classical vs quantum prediction from Wikipedia. It's wrong.
