OK... so when Hermione used the "Body-Bind Curse" against Neville in
PS, she was using dangerous "Dark Magic?" Even though that curse
actually didn't hurt Neville at all? And when James used a "scourgify"
jinx to choke Snape, that wasn't dark at all? Ginny's jinxes & hexes
against Zacharias Smith are cool & funny, even though they are "minor
Dark magic?" It doesn't make any sense.
