1: Most references to Leprechauns in the context of a debate about God are non sequitur.
So you assert. How about saying why?
2: The attempt to shoehorn them into such debate are often categorical errors.
See above.
3: Leprechauns are in the same category as other things things not scientifically demonstrated. A category which includes Consciousness, Dark matter, Multiverse, string theory.
You really don't have a clue, do you?
Leprechauns are stories that cannot be falsified and that have no supporting evidence or arguments.
Consciousness definitely exists but there is no complete theory yet.
Dark matter has evidence (gravitational effects on other matter).
Multiverse and string theory have arguments based on existing theories.
So no, none of them are in the same category.
4. Since Leprechauns are never mentioned in the context of the debate above we can conclude the reasons for there inclusion in any debate about God...argumentum ad ridiculum and therefore category 'fadiddling' which is something quite different from category error.
Nope. They are included because they share the same attributes of being stories that cannot be falsified and that have no supporting evidence or arguments.
Prior and dogmatic commitment to SEA is necessary for such behaviour.
No idea what this drivel is supposed to mean...
