Anyone older than 20 could probably list several cases of this.
But in the Traditional Catholic world, it's especially true!
Let's say the Crisis didn't exist (Vatican II never happened, let's say. Let's say all the modernists were persecuted and killed by some over-zealous Catholic monarchy in 1920! *grin*), and I wrote a work of fiction that described a great ecumenical council that totally changed the Catholic Church -- basically described the Crisis we're in today.
And further, let's say I included all the same minute details -- Abp. Thuc, Abp. Lefebvre, all the various groups, the Dimond Brothers, Pope Michael, etc.
And let's say one of my characters was a staunch sedevacantist yet a fervent follower of John Paul II's "Divine Mercy" devotion.
Altogether, the story would be so outlandish, all publishers would throw the script back in my face:
"You can't just make stuff up, man!"
"It's just not very believable."
"This doesn't make any sense!"
"I'll grant that you are a creative one, but..."
and other similar reactions.
And yet... that's what we all call "Reality" today. Amazing.
