You don't even have to go that deep to see why this analogy sucks. The year with the dementors was probably Harry's safest year as a student (yeah he was attacked by dementors and a werewolf but voldemort literally tried to murder him every other year. The only evil dude that year hung out in his dorm the entire time and fled immediately after getting caught without even trying to attack Harry)

unless this is some meta commentary on how the average student probably only cared about not being able to go outside because of the dementors and ignored the fact that there was an immenent threat of an evil superwizard (just like libs think Trump is the root of all problems and all of our problems will go away once Biden wins and covid is defeated)
