Fear Quotes Page 6
How we cite our quotes:
[T]he magical community lives in fear of a massacre like that of twelve years ago, when Black murdered thirteen people with a single curse. (3.56)
This idea of "living in fear" really sums up the magical community. We can see evidence of this with how people react to hearing Voldemort's name. It's like a whole group of people collectively decided to deal with their fear by ignoring it, or by trying to at least.
