Real ability? The fact that you so openly discriminate leads me to believe that you have a low opinion of "Indigo children" like they are bad or not intelligent.
You do realise that there are many forms of intelligence?
Do you also realise that there are many (very real) careers of a spiritual nature?
I don't understand why you think these gifts are imagined, just because you do not like or understand something does not make it unreal.
The thing is that everything you are saying can be applied when flipped to many other gifted children, ones that you consider "really gifted".
For example the exceptional maths pupil who has social difficulties...shall we take them to social classes because it is a fault or negative trait of theirs?
I'm not sure i believe in ordinary, people may have ordinary traits in some areas but will always have some that are not too. You can only isolate certain aspects that are ordinary and not lump the whole as ordinary.
I'm sure this will continue....
