I've seen allegations like this in other places I visit, and none of it actually attributed anything quoting Hegseth saying it was a "mission from God," "Christian Crusade," or "religious war."
Most of it has extrapolated that Hegseth is a Christian and says Christian things, therefore this is X. The worst one I read was an article written saying the same based off an anonymous complaint by an NCO about their commander.
If you can post the text I will read it, but right now this sounds like more of the same.
