Confessions are to be made voluntarily in church or in anywhere.
Some French psychoanalysts were daydreaming about Inquisition as if it was not a historical reality but a mere metaphor.
Your 'metaphors' may not hurt your 'loyal' readers but it hurts the other readers.
So one might need to rethink about why some people did not 'confess' even under fire. Nothing to 'confess', it was all in their head.
One might, as always, speculate if it was not a mere metaphor, but a calculated reference to some kind of forbidden 'art' called 'pyromancy'.
So people who don't know about pyromancy will see it as mere metaphor, but people who remember the 'art' will feel the burn in their souls.
Strawman may be immune to burning, but a strawwoman is not like that.
“Whoever may still be sceptical whether knowledge of animal behaviour can help our understanding of man can find no support from Freud.”
― John Bowlby, Attachment
"In rejecting Bowlby, his psychoanalytic critics on the other hand felt that by restricting himself to a narrow definition of science – to what could be observed and measured – Bowlby was missing the whole point of psychoanalysis."
