I would dispute any notion of souls in the sense of some internally resident supernatural entity as that is grade A woo without any real justification; it diminishes us all to suffer such superstition in a public space; unreason and dishonesty should always be given no quarter imv.
As it should be in any intelligent person's view. Sadly, not all intelligent people are immune to religious indoctrination.
And if the 'soul' defines something that isn't woo?
I have no issue with a casual notion of 'soul' meaning, the core, or essence, of someone's personality. But a notion of a 'soul' in the duallist sense, some immaterial being inhabiting my body, that's strictly woo.
