I wonder if the author realizes the Jehovah's Witnesses refuse to be drafted. In World War II Germany, they paid dearly for this refusal. Belief in a flat earth seems like a minor failing compared to the moral strength the Witnesses have shown in resisting one of the demands of "civilization" on its members.

Why?

To me it seems disrespectful and offensive to publicly shame your parents, or almost anyone really, over privately shared conversations and opinions. Reminds me of this time I had lunch with a co-worker, who repeatedly referred to his parents as being "uneducated" because they didn't finish college.
