One thing that bothers me that I cannot find anyone talking about

I forget which book it is in, but I think Ron tells Harry before they 
are sorted that "There is not a witch or wizard that went bad that 
was not in Slytherin."  What about Sirius Black?  He was in the same 
house as James, and at that time EVERYONE thought he was a Dark 
Wizard.  

Am I missing something?
