There has been a lot of debate on whether Snape is a Vampire or not.  
My inclination is, does it really matter? Of course not.  Snape is 
still a nasty individual regardless. (Though I think he is one of the 
most interesting and unpredictable)  I don't want to discourage 
debate on this topic, but I would like someone to tell me why it 
would matter if Snape is a Vampire or not.
