This is crazy, you can't make up fake statistics like you did, post them as fact, start a song and dance when we request to see your source for the claim, claim that you didn't make them up, and then continue the song and dance, finally admit that you made them up, and now start challenge me to prove they are fake.
I am very sure now that you are the guy who has pulled this before with these fake statistics, and your dishonesty led to the same reaction that I am getting from you now.
The mods can require a source for things posted as fact, I hope they do that with you.
And why do you insist that they are “made up” when you offer nothing of your own? The 40% is quite consistent with the demographics of the time. Combat arms drew heavily on an urban population that was heavily Catholic, and a population that, relative to the Protestants and Jews was underschooled. It had little to do with any superior patriotism, and every thing to do with the draft which was straining to supply the 90 divisions that were required to fight a world war at the same time as huge industrial force. It seems that this threatens the nativism that you spout, a prejudice that can be traced back to the late 16th Century when Britain became a Protestant state, a prejudicr that survives the dechristianization of that country. The figure represents assertion like that of the undeniable one that notes the high representation of Southerners in the military in the voluntary army.
