In most parts of the western world, women have full reproductive rights, but the father has no say, if she aborts the fetus and the father wants the baby then too bad for the father and baby, if he doesn't want kids and she decides to keep the baby then he is forced to pay child support or else he is put in prison.

Some of u might think that the father should be allowed to have a say and this can be settled in court.

Others believe that women should decide what to do with the fetus, but the father doesn't have to pay child support.

I personally, prefer the latter, as a libertarian I want to keep the government out of people's wallets as well as their bedrooms, I would like to have lower taxes relying on the sales tax and abolish the rest of the taxes, child support is taxation and the father is forced to pay up. I wouldn't have a problem with child support if it were voluntary.

Edit: By voluntary, I mean keeping the government out of it meaning no contracts.
