Racism and Snape's grudge

Stepping aside from the ping pong match for the moment, we 
have been treating Slytherin House's blood-ism as if it were 
purely a ploy to hold on to power. But what if that's not the case? 
What if Snape, for example,  sincerely believes that character is 
inherited? 

 Then he might believe that he himself has no choice but to be 
like his abusive father and  that Harry *has* to be arrogant 
because James was. Sirius, whom we know was brought up in 
a blood-ist household, also seems to have vestiges of that idea, 
and to think that Harry ought to have inherited a liking for risk 
from James.

 It's interesting where this might lead Snape with Draco, 
because it seems that Snape wanted to believe Lucius had only 
worked for Voldemort because of the Imperius curse. Now that 
Lucius's involvement with Voldemort is beyond question, it might 
be that for Snape to think it possible  to save Draco, he will have 
to  change his beliefs. And that might, in turn, result in Snape's  
seeing Harry in a different way, even if Draco himself does turn 
out to be nothing more than a chip off the old block.

who notes that the Chamber of Secrets, like the Room of 
Requirement, was able to provide Harry with what he needed. 
Maybe Tom only found a basilisk and a gigantic statue of 
Slytherin in the Chamber because he wanted to.
