Where's the justice!????

How is it just or fair that convicted child molestors are legally "entitled" to get visitation - albeit supervised in most situations - with their biological children?! I am outraged by this. I feel that they gave up that right when they CHOSE to take advantage of and strip the precious innocence of a child!!! What positive influence could they possible deposit into their children's lives? What benefit will it do the children to have to go to an office building once a week and sit in a closed room while their predator/offender father looks at them, talks to them, touches them - thinks thoughts about them!??? How is this just!????????? Something has to change. I just don't know where to start.....
