I wish I could gather all the pedophiles and their defenders and place them on an island and drop a few atomic bombs on said island. I would sleep better at night.
That's very specific. I'd love to know how you would accomplish such a thing.
I'd use modern technology. I'd create a large monitoring software that would be able to trace every step they make. I wouldn't mind creating a prison with several giant screens that display all their actions 24/7.
Killing pedophiles like that would not solve anything. There are more out there than you could affect effectively. It's okay to have feelings like that, but acting on it--and, even, sometimes voicing those feelings--drags you down to the level of the people you're condemning.
Are you nuts? That will solve everything that is a problem on this subject.
Wanting others dead only makes you a bad guy as well. You should let the justice system take care of them.
