Also you could go to a niche technical forum and find some of the planet's bes specialists of the material. For computing, you'd often see the people that built everything (from software to hardware). It was truly a world forum at a level that things like Twitter never got close to.
I don't think the US evangelicals really qualify as christians. They've created their own thing based on the same symbology, and have kept some of the names, but it has very little in common.
My SO can identify all actors by voice (she follows all films by ear because she's playing some kind of Candy Crush game — several of them, because she runs out of levels). And as a lot of them are foreign, and dubbed, she'll tell me that this was the guy that was doing the voice in (litany of roles).
Of course I have to pick films accordingly. She's never seen Tenet.
