Honestly, I think they truly believe that acknowledging reality actually is child abuse.
Here are the things I've recently seen fundies call child abuse:
- having them wear a mask during a pandemic
- teaching them accurate history that doesn't glorify white people
- teaching them sex ed or anything about how their bodies work
- allowing them to express their own personalities versus being whatever the parent wants them to be.
I think fundies would be happy if they could just officially own their children and treat them as property.
