"I think a worse moment for Snape is when Harry and Malfoy dueled
briefly in GoF and Hermione was accidentally hit and given huge 
teeth, and Snape said "I see no difference." Very, very uncalled for,
undeserved, cruel, and disgusting."

MmeBurgess:
I agree with this completely.  It is Snape's worst moment and one 
that unfortunately defines his character for me.  This is what made 
my earlier arguement about Snape being a good or, IMO, bad teacher.  
This moment has nothing to do with the necessity for discipline in a 
science-lab class, as was argued by houyhnhnm in 
http://groups.yahoo.com/group/HPforGrownups/message/132458.  I 
understand being cranky and snippy.  But moments like this in my 
school would warrent disciplinary action by my principal.  Perhaps 
houyhnhnm's school is different, but my system instructs us to 
create a "positive learning environment" in which "ALL students 
learn the material".  If this is not done, it doesn't matter how 
much you know or how much teach.  If the students don't learn it, 
you didn't really teach it.  Now, as a high school teacher who sees 
roughly 400 students per year, I understand that despite my best 
efforts to create a positive environment that brings down the 
affective filter, some students simply don't want to learn.  Others 
have jumped in above their head.  But, comments such as the one 
above do NOT create the necessary environment for affective 
learning, IMO.
