Some people think that Slytherins are cold heated jerks. like look at this quote
"Whenever I tell someone I'm a Sytherin they look at me like they're concerned. It's not like a 'Why do you care what fictional house your in in a fictional school in a fictional book' look. It's a 'Are you evil' look."
-Jay Carlin
Like what Is that? It's not only him. If you look you will find that ten's of hundred's of people that are Sliytherins have been made fun of. Wheres your kindness now Hufflepuffs?
Just because we had one or two bad people in our house doesn't mean were all evil!
This video says all I just said and more. Maybe after it you wont judge slytherins
