Are you saying that the woman choosing not to have an abortion isn't part of what you claim is her right to decide? Since the woman demanding someone else be forced to support the kid(s) SHE chose to have as part of what you claim is a right, it's as much a part of the discussion because it couldn't take place without her choice.
I'm not using the future at all. There are plenty of situations where the mother choosing to have a child already has children she can't support and is relying on those very people she told to butt out of her body choices to support them. Does she think having more will make the situation better?
This is just one example:

At the :50 mark, she says someone needs to pay for all her children. While only one baby daddy was identified and for 10 of her children, that means at least one or more baby daddies helped produce the other 5. Don't know how many and don't care. I can say two things with no uncertainty. One, those that produced the children with her need to pay and two, I'm not one of them, therefore, I'm not one that should be paying.
I've heard the argument that the children shouldn't pay for the sins of parent(s). You claim to be a Libertarian yet you have no problem with the government forcing those of us that didn't "sin" to pay for sins we didn't commit.
