Make no mistake: This new ideology is deadly serious. It is nothing less than a kind of cultural acid, eating away at the central pillars of a free and open society.

What happens when we can no longer openly dialogue, debate, and discuss different viewpoints because we fear offending someone who may claim our speech was "violence," leading to our public shaming or loss of employment? What kind of culture will this new ideology produce?
