This is tough...
If making self abortion illegal will promote the values of safety and health for women, then I support it.
However, nothing is ever this simple.
I agree with diamond splinter

that it should be illegal--- but a trip to the psych ward or jail
not required. A trip to the hospital to see if you are medically clear is in order. Sure, there may be other psychiatric issues, but just because a woman wants to abort and she may have barriers to that doesn't mean she's mentally ill.
So if we make it illegal, then something has to balance this; because women would not self abort if they had adequate resources. So we need to promote these resources, thus eradicating even the need for the law. Which is hard to enforce anyways.
Does any of that make sense?
