Use of Hagrid's name - More names

This whole discussion of Hagrid's name has been very interestig, and 
I don't really have much to add except a question.

What views do you take when you combine the use of Hagrid's last name 
with Dumbledore's incessant insertion of "professor" when Harry does 
the same with Snape?

Anyone have any views on the discrepancy in the way Dumbledore refers 
to Lord Thingy?  He tells someone--McGonagall I think--that we should 
use the proper names for things, and in doing so refers to Lord 
Thingy as Voldemort.  But then, when facing him directly, Dumbledore 
calls him Tom.

I don't think it's a respect thing, or a button-pushing thing, but a 
teacher-student thing.  I think Dumbledore is trying to reach the boy 
that was Tom Riddle before there ever was a Lord Voldemort.

Of course, if this is true, it means that the boy inside Voldemort 
*can* be reached which would imply some sort of temporal ambiguity.
