After thinking about it seriously…

I have similar feelings about abortion and legalized prostitution.
In both cases I hate that the demand exists. But I think the woman* has to make the decision, no one else has the right to decide for her. And if she does decide to, it should be under the safest circumstances possible.

*I get that not all sex workers are women, but it should still be the decision of the worker—and only under safe circumstances.
