So, I was a Christian for a big portion of my life, now an atheist for close to a decade, and I'm still finding silly things I learned as a Christian that I had yet to revisit up till now. The symbol of Asclepius and Caduceus had been synonymous in my mind and the symbols surely had to come from the biblical story of Moses putting a serpent on a brass rod to heal the Hebrew people. And of course that's nonsense since caduceus symbology is much older than any origin of the abrahamic religions, dating back to around the time the Sumerians were running around Mesopotamia. I'd imagine I could find that Judaic mythology found inspiration for this particular story in the same place the Greeks would find inspiration for their mythos a few centuries later. Either way, I find it ironic that American Christians insist on the usage of the caduceus for medicine as the "correct one" because bible, when in reality they're pushing symbology of the rich... again. Reminds me of when I was in bible college and we had a professor who went on a short tangent to remind us that nations will have their gods that they worship and America has that statue of a golden bull in New York, so America worshipped wealth. The irony in American theology is thiccc.
And just an anticipatory note: the 'brand' of Christian I primarily subscribed to before my deconversion doesn't consider any country to truly be a "Christian nation", as the only true one would be the "Kingdom of Heaven" established by Jesus, making any state that called itself Christian a pretender and a liar. It's less about demographics and standards of law, and more about remaining ideologically "separate from the world". A separation of church and state, if you will. Hence the premise of America not being a Christian nation in the above.
It's funny you say this since there is a fallacy fallacy, in which one assumes that the conclusion of the argument given must be false because the argument uses a fallacy. I think this usually comes from a place where people are looking for a gotcha moment rather than sincerely engaging with the topic, and I think the big pitfall of the fallacy fallacy is that it feels like you're engaging honestly and sincerely. So yeah, it's better to engage with people honestly rather than assigning malicious intent upon detection of a logical fallacy.
