We already know that they cannot all be. Tom Riddle was Slytherin, 
and he was a half-blood. Maybe things have changed since then, but I 
think that house choice has more to do with the way you think than 
than your blood. Slytherins are the people who's strongest 
motivation is to do anything to get what they want. The sorting hat 
chooses your strongest motivation, regardless of whether you are a 
pureblood or not.
