>Okay, here's yet more grist for the "abusive Snape" mill.  Would 
an "O" for Harry on the OWLS vindicate Snape's teaching methods?
>I hold that it would not.  Abuse is never justified -- EVER.  And 
behavior and teaching methods such as Snape's are never justified -- 
EVER.  The effectiveness of them, if they are effective, is no 
defense or vindication whatsoever.  Snape would still be absolutely 
in the wrong to employ such methods, and Dumbledore would still be 
absolutely in the wrong to allow them.<

Okay, I'll bite.  But first I have to ask, what abusive methods?  
Making Harry call him sir?  Demanding potions be done correctly?  
Disliking class disruptions?  Throw some canon at me, because I 
seriously don't know what you're talking about when you say "abusive 
methods".

And yes, if a teacher's students learn what the teacher is teaching 
I'll call that effective.
