Here is the deal. Right after a baby is born, it would be considered murder to kill it. However, two minutes earlier when it was being born, it would have been perfectly legal to kill it (only in some US states). This is known as "late term abortion". Anyone with IQ above 70 should be able to see that this is completely ridiculous. So we need to work our way down the line. Why is it wrong to kill people? Because you are depriving someone of their life without their own consent. You are essentially stealing the most precious thing any being possesses, which is life. There is nothing more precious than life and to steal this is one of the worst crimes there are. Hopefully we all agree then that killing a new born baby is 100% wrong. So what about right before it is born? I see absolutely no difference. If you do, please explain. Going further back into the pregnancy, does this ever change? At what point is the baby suddenly "killable"? Should it be legal to kill the baby on day 50 but illegal on day 51? How much sense does this make? Let's step back even further to conception. The entire human is there once the embryo is formed. Before the embryo there is only an egg and millions of sperm cells trying to reach the egg. Now let's say a bunch of sperm cells are racing to an egg. Suppose you had the power to kill that egg. Would you consider it immoral to do so? You aren't aborting a human but you are aborting a future human. Is there really a difference? After all the only reason it would be wrong to kill a fetus is because you are robbing it of it's future life. Due to it's undeveloped brain a young fetus really isn't much different than a mouse. It is only because it will one day grow into a human capable of experiencing life, that it is wrong to kill it. So back to my above example. Wearing a condom is essentially what I described above. When you do this you are basically depriving a future human of its life. Same with a vasectomy and birth control. Please remember that when you wear a condom you are killing a sperm cell that would have become your child. You'd one day be reading a book to that child, teaching them how to drive, or waving goodbye as they move away and start their own family. But you decided to wear a condom, so that never happened. How is this any different than abortion?
