This isn't even a case of "even my enemy deserves prayers..."
It's true that our enemies need prayers, but come on!
Let's be real: I would agree with Mark about 99.9% of issues in the modern world today. If I were dealing with *any* random group of people and then was placed with Mark (in any group setting, at work, etc.) it would be a breath of fresh air, like I was back home, among family, etc.
The same is true for any one of you. Unless you live in St. Mary's KS and have tons of solid Trad friends and family (with whom you have ZERO disagreements), you would probably be ecstatic to be told to work with someone like Mark.
We should keep in mind just how much we have in common here. It's that 1% or 1/3 of 1% of stuff that we all squabble about endlessly, and get red in the face about.
