Did Ben Shapiro explains there must be a secular reason to justify everything?

You should ask yourself is he suggesting something that does not pass through secular peer review should not be used in a debate or discussion?

If so you should keep in mind that Ashkenazi & Sephardic so called Jews are able to control the peer review process

A so called secular reason monopoly provides a way for the so called Jewish religion to have a viewpoint monopoly in all conversations without being secular
