"Your Body Your Rules" is a lie. To begin with, we did not make ourselves. We have been made by the Creator and therefore our bodies, just like the rest of creation, belong to him - not us. Secondly, our Creator has given us rules. They are called the Ten Commandments. And those Ten Commandments tell us that we are not to indulge in sex outside of marriage (another thing initiated by the Creator and not us), nor are we to murder.
This whole "it's my body and no one can tell me what to do with it" idea is a recipe for a dysfunctional and wrecked life - not to mention death. I wish these people could see that they are driving away from themselves the very life and love that their hearts crave. Sad.
