Within many faiths, there are teachings about “the mark of the beast” or man not changing what the divine hath wrought, etc., without a lot of specificity.pretty sure religions really never mention vaccinations.... until a bunch of antivaxxers made their own 20 seconds ago religion with that purpose.
’Cause just like modern legislators, the people who wrote those down knew too much specificity in drafting rules meant it was easier to find loopholes to them. In a sense, vaguer is better in some cases. So there’s rules against cutting hair, or not cutting hair, against piecing or tattoos, what & when you can or cannot eat, what you can or cannot wear, and so forth.
Couple that with things like prophesies and so forth, and anything new and scary can be designated as against XYZ’s religion.
