I've been married 15 years and known my in laws for longer. I'm an agnostic. DH is even stronger into the atheist camp. Religion isn't something that our household focuses on.. it's akin to saying something about cricket if we don't follow it.. not a controversial topic, just irrelevant.
A certain in law has become extremely religious during the pandemic, to the point I'm not comfortable, especially exposing our DC to them. Everything conversation wise gets routed to religion (a pure Christian firm, very orthodox, questioning evidence of science, medicine etc, world isn't more than a few thousand years old theories etc).
I'm concerned at the constant turning of every day topics into religious debate when we visit for care during lockdown, to help them in elderly care matters. I swear if I said it might rain I'll get "god willing" in response. Or if I say the carrots look nicely cooked I'll get "thanks to the lord" ... Everything is turned to scripture, and I didn't sign up to this type of family dynamic. DH thinks it's harmless batshit from a family member who's going a bit odd, I think it's frustrating and bizarre and actually harmful for every single innocent conversation to turn into science Vs religious debate (I, so far. Simply change the subject and ignore, I will not debate).
Aibu to want to reduce contact with this relative / in-law, despite DH thinking it harmless, because of DC..?
(DC do not really know what religion is at 2 but I'm worried they'll pick up distrust of doctors etc)
