You're not alone. There are some things that I can't watch in my entertainment, and extended deception is at the top of the list, truly tied with guns, violence, and the suspense-vibe that implies violence is about to happen (even if it never does). Deception isn't the same as false accusations, but I think it might be a cousin, in this context.

I don't think mine is tied to a particular childhood trauma; I think it's just one of my points of vulnerability as a person.
