AITA for siding with sister/mom over fiance
My (35m) fiance (32F) is weirdly religious. Like she's a catholic and for the most part is tolerant and accepting to other people's ideology. Mostly. There's only been one thing that she gets unhinged about.
She hates dinosaurs and does not believe they existed.
Why? Because they weren't in the Bible. She believes fossils are either animals with defects (ie: triceratops being rhinos with birth defects/mutations) Or that the fossil was literally planted by Satan for the long con game of turning people away from God.
For whatever reason, dinosaurs cause her to go full Bible thumping mode. Like think Westboro but against dinosaurs.
For the most part, it hasn't been an issue because dinosaurs aren't something brought up. And in the occasion that dinosaurs are brought up, i usually have no opinion and let her go off on a tangent.
Enter my nephews (6m) birthday. Over the weekend it was his birthday party. And it was dinosaur themed. We didn't know this and it was nothing malicious because dinosaurs aren't brought so they didn't know
My fiance turns red seeing the dinosaurs and I tried to nip it in the bud and pulled her into the kitchen. I tried to get her to drop it today because it's a kids birthday, dinosaurs ate a common thing for kids. But she was complaining about it saying my sister was turning kids away from God and Jesus because Satan fossils.
My mom and sister came into the kitchen and overheard us arguing and what she was saying. They both thought she was joking at first but when by fiance accused my sister of promoting Satan and being insulting about her parenting as a result of not being a true catholic, it turned to a fight real quick.
I tried to calm things down but it got worse and finally I told my fiance to stop being a psycho. Dinosaurs were real and she was being crazy for trying to have a religion war over dinosaurs at a kids birthday.
She called us all a bunch of fake Catholics and closet Satanist and left. I tried to do damage control but she pretty much is banned from foreseeable family gatherings. But now my fiance is also pissed at me saying i should have supported her, even if i didn't agree, and tried to save the kids from Satan by preventing exposure to dinosaurs.
But dinosaurs did exist and her Satan fossil conspiracy theory is crazy. So how was i supposed to support her when she's wanting to go crusading about it at a kids party? Was i the asshole?
