But we do not have to give in to desire, ours or theirs. With sex comes the risk of bringing another life into being and we are responsible for that life. It strikes me that abortion is no solution to the problem of irresponsibilty. Deliberately harming or killing another outside of self-defense is wrong. It is also not necessary.
Abstinence is the first common sense step.
The next wide level of choices is birth control. Women and men fought long and hard to be able to determine and rule their own reproductive systems. Both Church and State, usually hand in hand, have wished to control people by controlling their sexuality and their ability to reproduce. This is historical fact. Without access to birth control and the knowledge of how to use it correctly, there will be infanticide, abortion, and unwanted children.
