I honestly have no idea how that has anything to do with what I'm saying.

And I read all the books, and watched the first six movies. I know what the prohesy is.

You honestly can't see how knowing someone is the chosen one destined to save the world from the evil one and who quite possibly already stopped a war impacts on the likely behaviour of a character? Implied via that same knowledge is that Harry has the favour of McGonagall's immediate superior.

It should be overwhelmingly obvious to you how this information is relevant to what you are saying. Any judgement made without considering this context is absurdly ill-informed.
