What punishment should rapist get if they rape children?

A rope and the nearest available lamp post.

Full public caste-ration ,with a very dull knife,maybe that would send a message!

due process, life at hard labor if found guilty.

Impaled.

if it is a male doing the raping, then castration.

If it is a female doing the raping, something equivalent.

Death by rape.

Elected to the Senate?

They get put in stocks alone with victim for as long as she needs vengeance free to do what she wants. Then every thing he is worth is sold and the proceeds goes to the victim. Then locked up for a while.

The question implies that the person is clearly guilty.

In that case, something terrible.

But it won’t change the past…

One month alone with me in the torture room.
