How is it unfair again? Did the man suddenly gain authority over medical decisions because he f**k her? No, of course not...
So what exactly makes it unfair? The only possible answer is that he disagreed with her decision... and from this, we conclude it is unfair to the man.
Total bullshit. You have no say over what a woman does with her own body. You have no say over that fetus. That is imminently fair because the woman f**k carries it. The only way to deny this conclusion is to deny the fairness of the womans right to choose, and I haven't seen a single reason given for why that is unfair that doesn't revolve around the fact that penises can't eject babies.
