should sex dolls that look like kids be banned?

[nclib]

It seems like there are two unproven hypotheses here:

1) Using a child sex doll will lead towards a pedophile offending a real life child
2) Using a child sex doll will give an outlet to a pedophile and decrease the chance of their offending a real life child

Since both are unproven and it is not obvious which is more likely, I'd say not to ban them.
