Those are great points! Yes, it makes people uncomfortable because it hits close to home. I completely understand what you're saying.

But then, in a way, the whole Death Eater business waters it down, makes it tolerable and not as uncomfortable. If you mix that with an air of "coolness" to be a Death Eater (e.g. Lucius) . . . well, you can see where I'm going with this.

Over analizing of course, but I'm playing devil's advocate. ;-)
