To be fair, celebrating war criminals in places of worship is not exactly a new phenomenon.
I’m maybe going to dox myself a little bit here, but… story time:
When I was a child I was shuffled between various juvenile placements for several years. One group home I lived in was truly in the middle of bumfuck nowhere. Legally, they were required to make reasonable accommodations for worship arrangements. If you were on some sort of restrictions for being a bad kid (which of course I always was), getting shuttled to the non-denominational church a few miles up the road on Sunday morning was the only opportunity you had to get off the property for the week, so no matter your beliefs, you said you were Christian just to get out of the house.
Anyways, one Sunday, the pastor had a guest speaker — a missionary who spent time in east Africa, the Middle East, France, and England. This missionary spent the entire sermon glorifying Bush’s spiritual war on Islam and warning of the rising tide of Muslim extremists. Specifically she warned of the ever-growing Somali population in the major metro area some 200 miles away from us. She spoke of the carnage being wreaked in Paris and London — how these bastions of white Christiandom were being taken over by depraved, animal Muslims. That if we were righteous Christians, we should support a certain political candidate in the upcoming presidential election… that we needed to become, quote: “An Army of Christ” and quote: “Literal warriors for Christ”.
I was too young at the time to really understand wtf was going on. I assumed they were a single ultra-crazy person in a sea of mostly sane people. I wasn’t able to see it as the simmering origins of 21st century white Christian nationalism and modern day fascism that it was. Bear in mind, this was a dying old railroad town of 600 people at this time, yet the Christofascists were sending speakers to these tiny little shitholes to stoke fear in the hearts and minds of the working class to amass an army of white Christian nationalists.
Anyways, all this to say, houses of worship have celebrated war criminals since… well, when did the first organized religions emerge? 10,000 BCE give or take?
