His real enemy is not Trump, the GOP, or the Tea Party. His real enemy is God.
"I'm an atheist. An agnostic is someone who is not sure. I'm pretty sure. I see no evidence of God."
George Will
Will has fought his battle with God for decades, it's just been far below the radar. When you hear him speak, the only thing he seemed to worship was the Alex Hamilton, baseball, and his own ego.
He has completely rejected the Almighty. He is angry at God that his son was born with Down Syndrome. He is angry at anyone who professes a belief in Christ.
