Let me see if I have your position correct with a couple of hypotheticals:
1- My girlfriend and I decide to have a baby. Three months in to the pregnancy, she changes her mind. She kills my child, and I have no input.
2- My girlfriend and I decide we don't want to have a baby, and agree to use the pill for contraception. Without my knowledge she quits taking the pill because she now wants a baby. Ninth months later, a judge tells me I have to pay child support for 18 years.
Is it your position that in either scenario it's none of my business?
