I am personally against abortion dee but that has no bearing on this issue if your going to give the choice to one logically you must give the choice to the other.
the morality of abortion doesnt come into play here dee simply fairness under the law.
Your idea of fairness under the law is how society used to function. It worked like this.
Under your premise, you have no responsibility for any child you father, because the option of abortion exists. Therefore, you're no longer responsible for birth control, at all, because any child born is the woman's problem. Also, you can go out and get 30 women pregnant for all you care, because you aren't responsible for any one of them. It becomes the tax payer's responsibility. And the woman's. She needs to be punished in that case.
Sounds good to you? Fine, just don't talk about equality, because that ain't it.
