Well , in the case of there being ondemand abortion Imagine a situation that your one night stand has come to you and said I ' m pregnant , and it ' s yours , and I want to have it . You say to her , I completely respect your decision , but it ' s your decision . As another sovereign individual I ' m going to lodge with the HSE or whoever , that I personally am not supportive of this , and won ' t support you or the baby , if you choose to have it . The logic being if the mother is the only person who has a decision , she would be the only person with responsibility . Why would the man be held hostage to whether she chooses to have , or not have a child . Accepting the Mother ' s monopoly of the right to choose , not the right of the Mother to get 18 years child support because she chose to have it . It ' s the inverse of the situation where I as a Father may have wanted the child , and the Mother aborted it , because the Mother has total responsibility for the decision .
