One of the most common themes not just in Harry Potter, but also in all wizarding world stories is the intense dislike and antipathy felt towards Slytherin house and it's members. The fact that most of the antagonists throughout the series are from Slytherin and the fact that Slytherin is disliked by all the other houses (especially Gryffindor who it shares a rivalry with) also doesn't help either.
Who do you think are the most anti-Slytherin characters throughout the series?
In my opinion it's either Hagrid or the Weasleys.
Tell me yours!
