Wouldn't surprise me. The actual number of people among the major religions who buy into death cult shit is pretty staggering, especially among politicos. They're smart enough to keep their traps shut to appear moderate and preserve influence, because they know if they were vocal in public they'd be unceremoniously shepherded out of public service and (preferably) into padded rooms. Worse is they tend to draw strong, quiet, support from the non-crazies in the Sam Harris "no, moderation doesn't really exist in religion" sense.There are serious questions about whether Australia's previous Prime Minister believes this, or whether he is just impressively incompetent and malicious.
Look at Mike Pence, he's practically the Aristotelian ideal of masked Christo-fascism in contemporary US politics. To the point of being floated as the sane alternative to bog-standard, blowhard, empty-suit, corporate bobblehead conservatives like DeSantis, Abbot, and Christie. The churches he attends/attended in Indiana preach some terrifying shit -- like "Charles Manson-adjacent" shit. There's good fucking reason he stopped attending them in 2013 when he started entertaining his presidential bid, while those churches scrubbed online presence and heavily laundered their reputation.
I live about two hours' drive south of Indy, and since high school I've only been peripherally aware of what goes on in Christian Hoosier Land, getting my info second- and third-hand from friends and family who still attend church. Even the fundies down here think those churches in Carmel and Indy are scary, and I'm not talking about the "northern and southern Baptists glaring at each other from across the liquor store" way people of different denominations just talk shit. I'm talking about evangelical, ultra-conservative, Christians who double-fist that fucking Kool-aid in almost every other circumstance, yet openly speculate if Pence might be the Antichrist.
