Why are men not allowed to choose if they become a father or not?
Unprotected sex and the man's desires do NOT 'force' a pregnancy and motherhood. Whereas, unprotected sex and the woman's desires CAN 'force' a pregnancy and fatherhood.
Too many women who are looking for the perks and benefits of parenthood without the trials and tribulations of a relationship and these women aren't looking for a father to their child, instead, they are looking for someone who can father their child. Too many women are making irresponsible choices by choosing (and forcing) irresponsible men as the fathers of their children; children that most men haven't agreed to.
There are few accidental pregnancies. A woman has a multitude of ways to avoid pregnancy and all girls have learned about birth control from puberty (or earlier). Men are not getting women pregnant. Women are getting pregnant by choice… and they are choosing their partner(s).
Oh, wait! Are you talking about abortion? Men aren't deciding what a woman does with her body; there would be so many sex slaves if that were the case. Abortion bills are trying to prevent the epidemic, systematic, consequence-free killing spree of millions of unborn babies (fetus, zygote, offspring, next generation).
