The "Slytherins are completely evil... except it's totes OK if you get sorted there Albus Severus!" will bug me until the END OF MY DAYS. Tell me, if the house is 90% evil asshole then why does it even exist? Or why don't they use it as a means of sussing out future criminals that they can imprison because that's practically what they're doing anyway. As a person who heavily identifies with the house (well, at least the characteristics I can suss out that aren't "evil") I am so bummed man. Ambition isn't the only trait that can have negative connotations. The three other houses all have traits that can lead one down a dangerous path (forever convinced that Umbridge is an evil Hufflepuff).

Haha as a fellow member of the big hair club I feel you on the point about Hermione.

I would read your book about Andromeda Blank Tonks.
