Which House were James, Sirius, and Remus in?

No: HPFGUIDX 88570

Let me respond to some of the suggestions made against the idea that 
the boys were in Slytherin:

(1) MaGonagall saying that everyone in one House were "one family" 
so James would not treat his "brother" Snape like that.  Just 
because they were in the same House doesn't mean they have to like 
each other.  Not all family members love each other.  Sirius was 
alienated from his real family.  And sibling rivalry is not rare.  I 
have no trouble thinking that Snape and James hated each other even 
if they were in the same House.

(2) What James did to Snape was no worse than what Fred and George 
did to Umbridge.  Maybe.  But I still have trouble seeing Fred and 
George sending their best friend off to kill someone who doesn't 
know what he is doing, like Sirius did with Remus, as one of their 
jokes.  I think a whole different level of nastiness is involved.

(3) Well, maybe James and Sirius seem like they are in Slytherin but 
REMUS doesn't and so they all weren't.  I haven't paid as much 
attention to Remus as the other two so I don't know how to respond.  
But I do remember that some time back, there were some postings here 
on the possiblity that Remus zapped Sirius through the veil, not 
Bellatrix.  (I can't find them with the "Search" function -- I can't 
find anything with that "Search" function.)  So some people must 
have seen something Slytherin-like in Remus's personality.
