I see your points, but I have something to add to the reasons behind snake handling.
Every minister generally wants to fill pews in church on Sunday.
With this in mind, people often have a gruesome side that makes them want to slow down to look at car accidents. This impulse is probably related to the same reasons why people like horror movies.
So . . . snake handling may be a gimmick to fill pews with people who secretly want to see if someone gets bitten and/or dies.
I ran this idea by an Evangelical Christian friend of mine, and his answer is that itās such people who need church the most.
My cousins are lunatics. Their ancestors, a splinter from the original immigrant families, voluntarily settled near the last operating lead mine in the US.
Itās selection bias, usually using a post hoc ergo propter hoc fallacy to rationalise it. āI prayed to a deity for the snake not to bite me, then the snake didnāt bite me, ipso facto goddidit.ā
As you say, when the snake has a bad morning, and shows itās displeasure, suddenly god is mysterious. You canāt dent a rationale like that. Plenty of people handle snakes without the pretence of a watching deity, and come to no harm, but then they have usually studied the reptiles for years, and have a deep respect for what they can do.
