Before Leprosy was cured, all the lepers would be sent to live together, away from the rest of the world. It might seem cruel by todays standards, but a horrible, killing disease is what it is. And, someone infected might as well be that disease walking.
Today we have several horrible diseases plaguing the planet. We have HIV spreading across the globe, for example. We don't put people with HIV into special camps. No, instead we just tell them, "remember to wrap it before you tap it." Meanwhile, the little AIDS demons continue to laugh at the world they may some day cripple.
Now, I'm not suggesting that we lock every with an STD up, but shouldn't there be some accountability? If you are walking around able to cause such an ammount of death and destuction, you'd think someone would say, "Hey, you better own up to this."
Crazy people are still punished for killing people, but is it a crime to know you have HIV and sleep around anyway? If you knock someone up, you have to support the child, but do you have to pay for their HIV medications if you infect them? People in this country won't even where protective masks when they have a bad cold, so why should I expect anything reasonable?
