Guys, enough posts contemplating what kind of 90’s pop culture that Harry Potter and his friends liked the most. All of Harry Potter’s classmates were uneducated hillbillies with zero knowledge of 20th Century technology (They don’t even know how or why cars work, for crying out loud! How the hell? Have they never seen a road before?). Even a static poster of a soccer player confound the hell out of them. Do you really think they had radios or televisions in the dorms? Do you really? What makes you think Hogwarts students had any contact with the outside world at all?
tl;dr: The Wizarding World of Harry Potter™ is basically a pagan snake-handling cult.
