The Shrieking Shack Incident

This is my entry for the contest held by @FUDGE-SNAPE! During the course of this book, I have decided to counter-argue against Snape stans' claims about Snape and put forward my reasons why I think those claims are wrong.
ALL THE FACTS WRITTEN HERE ARE DOUBLE CHECKED TO INCLUDE ONLY CANON FACTS FROM THE SERIES AS WELL AS POTTERMORE.
Lastly, if you want to participate, become a member of the Fudge Snape community now!!
You are allowed to have your opinion and I am allowed to have mine, so arguments and disagreements are common and a sign of a healthy society, but make sure you ARE POLITE AND ARE CONSIDERATE OF THE OTHERS.
