In America Today, girls and boys lose virginity at age 14. In doing so, they are just having fun. They're intentions are innocent. Yet, when we as adults do the same, we are shamed.
Common sense would suggest that consenting to have sex is consenting to have sex. To say it is anything more than that is wrong on the part of a lady. For a woman to carry a child to term is even more egregious.
In American law there is a term called "Breach of Contract" One idea of this is that if someone changes the terms of a contract or violates it...then the contract is null and void.
Thousands of lawsuits are based on this. Even marriage. If someone cheats in a marriage they can be granted a divorce.
Women are having one night stands or having sex with boyfriends outside of marriage. They are opening their legs and accepting the terms of having sex just for fun or pleasure. Then they get pregnant and blame a man for not "stepping up" when choosing to violate the initial terms of consent.
These days its even worse. Some 1% of girls in the country have sex with a guy and then change their mind because they cheated on a boyfriend and the boyfriend found out, or they feel embarrassed, or they have a negative social status as a result of their consent..then they change their mind and declare rape. Say this never happens? Take a look at the Duke LaCrosse case.
What is the logical or philosophical argument for why women have a right to universally force a child to be born without a father (or LGBTQ wise 2 parents)?
