You also forgot to mention that there are easier ways to use contraceptives. I was going to say cheaper but since ALL taxpayers are picking up the bill for abortion.............Women have full control over their bodies.
If you are implying they have control over the other body inside them, no... that body also has autonomy, and when the single individual nature has charged with keeping it safe is the same one that wishes to kill it, the law should step in and say no. Now, certain states can make the decision to do so, and others can make the decision not to.
The average human has one heart, one brain, two arms, two legs, ten fingers, and ten toes.
When that description changes to double all of the above as being one human, then your point about "their body" might have some merit.
