When to laugh at the ridiculous? Reviewing an atrocious book

Today it seems that cultural and political elites are racing break-neck toward the outrageous. The outrages of Donald Trump, Barack Obama, and Bernie Sanders would be hilarious if they weren't dragging us along with them. (Not Hillary. There's nothing funny about Hillary.)
As bad as the politicians are, academics are even worse. The next generation of minds is being molded by an elite cadre of people who get paid to think thoroughly ridiculous ideas and who think that all right-thinking people agree with them because they have insulated themselves from those who possesses common sense, not to mention elementary formal logic.
