Allie:

The Room of Requirement ITSELF changed the hangings to reflect who was 
living in the room.  Neville states, "...when I arrived, it was a load 
smaller, there was only one hammock and just Gryffindor hangings.  But 
it's expanded as more and more of the D.A. have arrived."  (DH 377 US)

Which means, to me, that there are no Slytherin hangings because there 
are no Slytherins hiding out in the room.  It's not a statement that 
all Slytherins are evil.  It just says, "No Slytherins live here."
