After looking at the question Is Slytherin Evil?, it got me thinking. The loudest Harry Potter fans I see online all seem to be from Slytherin and they are so proud of it. I've seen people from the other houses, but it's not too hard to find some Slytherin shouting something about having pride in their house. I've heard people complain about others looking down on Slytherin and that the world mistreats those in Slytherin. Those from Slytherin try to say it's really about ambition and becoming what you want to be, yet we see so many examples in the books where they bully, they torture, they kill, they do whatever it takes to be what they want to be.
Yes there are a few examples of people from Slytherin who weren't evil (Snape, Slughorn, Regulus Black). Yes there were people not in Slytherin who were evil (Wormtail). So I get that Slytherin is not inherently evil.
But I don't really see what they have to be proud about. Who from Slytherin is really, truly that accomplished? Just Merlin? Anyone else? Can you really be proud of being in the house that
generates all the most despicable people like was also the house of Voldemort and Umbridge and Bellatrix? What I am missing?
What do people have to be proud about in Slytherin?
EDIT: I see now how this question is fairly opinion based. I apologize for being rather biased and blatant about it. I think I see better now that Slytherin is really not evil, and that ambition can mean good things more than bad things. Thanks for the help!
