Yay! I don't have a ton of friends, but at least one is a Slytherin (two now you're here!) and they're awesome! Honestly, the only reason Slytherins are stigmatized is because Voldemort was in that house. The death eaters came along not because they were Slytherins, but because they were close to old Moldy Voldy. And then their kids were taught by their parents, so it was really all Noseless' fault!
