Are there any theories you would refuse to accept as canon no matter what?

For me it’s nightmare gas. I just can’t get behind it and find it to be so stupid. I’ve never liked the idea that Michael was the protagonist of FNAF 4 but that’s another thing. The idea that he was due to nightmare gas ruins the lore for me, but apparently there’s a strong chance it is canon now and I really don’t want it to be.
