You’re not going to split hairs out of this one. Trying to say that these are not Evangelicals because no true Evangelical would do this is pretty much the "No True Scotsman " evasion. When people say, “Evangelicals”, this is exactly the group to which they are referring.
The one or two “True Evangelicals” in the US can consider themselves exempt from this thread.
Take a look at this:
This is in the Museum of the Palazzo Massimo alle Terme in Rome, and it comes from an ancient Roman Villa in Rome. Probably painted in the first or second century CE. There’s walls of this stuff in the museum.
It’s not realism, but minimalistic sketches that, in many ways, outdo realism in artistic quality. To me, this looks more like something that you might find in Leonardo’s sketchbook than on the wall of on ancient Roman Villa from 1200 years earlier.
