Caption is "OK, you want religion in schools. But that means all religions, right?"
Image is a library with a group of eight children dressed in black cassocks with peaked hoods sitting cross-legged around a pentagram drawn on the ground.
EDIT: The pentagram is partially obscured by one of the children but one can infer that this must be AI generated and botched (as per the comments in this thread).
The contradiction is that religious people don't believe in other religions.
My truth is the only truth and your truth is just barbaric nonsense!
I reject your reality and substitute my own!
