The last I can dispose of easily as this is not a research journal and so research is not called for.
But 'why do I speak with authority' is more interesting.
I speak as an oracle. I simply describe what I see.
And what I see may be right or wrong, silly or profound, in good or bad taste.
So I share with you what I see without a critical filter. And this is where you come in. You apply your excellent critical mind to what I see.
And the critical mind is part of the digestion process of analysis, evaluation and integration - so we can be free again to see the world afresh.
