“The Death Eaters can't all be pure-blood, there aren't enough pure-blood wizards left," said Hermione stubbornly. "I expect most of them are half-bloods pretending to be pure. It's only Muggle-borns they hate, they'd be quite happy to let you and Ron join up" "There is no way they'd let me be a Death Eater!" said Ron indignantly...."My whole family are blood traitors! That's as bad as Muggle-borns to Death Eaters!" "And they'd love to have me," said Harry sarcastically. "We'd be best pals if they didn't keep trying to do me in.”
“Let muggles manage without us!”
“Don't let the muggles get you down.”
“The wizards represent all that the true 'muggle' most fears: They are plainly outcasts and comfortable with being so. Nothing is more unnerving to the truly conventional than the unashamed misfit!”
“Wizards are a secretive lot.”
