When you use the term absurd, you have to show facts that support it. Maybe the files of the Catholic league, or some other apologetics site have a quick reference. What I have given is a truism generally know forty years ago. By and large Catholics in the US were not middle-class until the ‘50s. This is why the ranks of the infantry and marines were disproportionately filled by men of that faith. Ditto, Southern Protestants.
No one knew that “forty years ago”, 40 years ago I was a combat instructor in the army and the Vietnam war was going on.
I had been a military obsessed reader all of my life and especially of WWII, every male in my family served, my dad was already military when WWII started, my step dad served in WWII, my brothers and step brother served during Vietnam, I have an interest in military history and WWII.
Show your proof for such a bizarre claim.
