> The mainstream Christian theology is that Jesus will return in order to wage war on non-believers and secure earth as the heavenly dominion of the believers

That's really not the case, not in the literal sense anyway. Also pretty much all mainstream Christians do not spend any significant amount of time thinking about when will Jesus return and and what will happen then.

> Then Jesus can come with his flaming sword and slaughter ~billions of people.

I bet if you asked the pope what he thinks he'd say that's not what the Catholic faith teaches and he's literally infallible (well technically only in very specific cases but let's just ignore that since we're just saying stupid edgy stuff for no reason).

You must think you're deboonking by linking random Bible verses and obscure theory most people have never heard of?

I'm agnostic but I was raised Christian in different communities and on different continents and I have never been taught that Jesus's return is anything but a peaceful end-time where the just go to heaven (and yes, the wicked to hell). Zero mentions of Jesus waging war, if anything it's taught as the end of war and strife.

Not a single person I know associates Jesus with doing violence. I'm sure someone must believe this, but calling it "mainstream" is bad faith. What sort of "mainstream" theology is it if neither me nor anyone I know has been taught this?

I have no reason to think that the number of people who believe that "strong Israeli state will hasten the rapture" is not in the single digits (%) or more likely even way less than that.
