"I would have no objection to a prisoner being able to provide sperm for a none prisoner "
What about parental responsbilty? Many of these children would end up being supported by the state anyway. Its one thing to become a single mother through bad luck, totally enough to deliberately become a single parent. I have no objection to a non prisoner using sperm donation if she can financially support a child on her own.
A lot of people in prison are in prison because they are utter scum. Do we really want to enable them to pass their loser genes on. Its hardly a good role model for a child to have their Dad in prison.
"Some of you seem to think nobody in prison could possibly be in a relationship that began before they got banged up. That seems to be the only explanation for the constant partner blaming. "
Prehaps if the partner is desperate for children then she needs to find a new partner. She needs to find someone who will be a parent to her children and financially support her children.
