Do Google and Facebook engage in what lawyers call viewpoint discrimination? There’s some pretty good evidence that they do. Consider the lawsuit that radio talk show host Dennis Prager is bringing against Google. He alleges that YouTube, owned by Google (and its parent company Alphabet), puts his Prager University videos in restricted mode, but does not give similar treatment to videos from liberal sources.

Anyone familiar with Prager’s writings knows that they’re intellectually serious and far from abusive. He is a persistent but temperate advocate.
