   I would just like to point out that Slytherin is not the sole 
breeding ground of bullies at Hogwarts. What else would you call 
James and Sirius? 
 
   As I see it the problem is not so much the House system as such as 
the unhealthy level of hostility and competition that has built up 
over the generations, especially between Gryffindor and Slytherin. 
The Hat's song strongly hints that that conflict must be overcome for 
the good of the school and the WW.
