Only Slytherins Go Bad??

Rowena:"That's what Hagrid says in SS, at a time when he thought 
Sirius Black was a DE, and of course we know that Peter Pettigrew 
really was, so - are they Slytherins?"

James Potter isn't a Slytherin, nor is Remus Lupin. Sirius could be, 
but it seems to go against what we see in canon: people tend to 
socialize in their own Houses.  OTOH, I have a hard time seeing 
Pettigrew as a Gryffindor.

Rowena:"But what about Sirius? According to Dumbledore 
resourcefullness, determination and a disregard for the rules were all 
traits Slytherin wanted in his pupils and Sirius certainly has those 
in spades...."

When Dumbledore said those worlds, he was telling Harry how Harry had 
those qualities Salazar Slytherin valued; so Harry may not be the only 
Gryffindor with those qualities. Also, we meet Sirius after twelve 
years of hard time, which was bound to darken his personality.

Painting Slytherin with the brush used on Voldemort seems eerily 
familiar this week, while police stand guard around mosques to protect 
Muslims from hate attacks. We've heard other prejudice against the 
Slytherins:

'Isn't it obvious all this stuff's coming from Slytherin? The Heir of 
Slytherin, the monster of Slytherin - why don't they just chuck all 
the Slytherins out?" he roared, to nods and scattered applause.'
