Abortion is usually committed as soon as a test is taken, or about 5 to 6 weeks into a pregnancy. By this time there CAN be signs of a heartbeat taking place. Basically, during this time the only think that is classifying that substance in your stomach as being a "baby" is the "heartbeat" nothing else. You can not murder a cell.
Although I do understand what you are saying, a person was responsible for dropping the bomb. No weapon goes off without someone touching a trigger. If a gun were to lie on a table and shoot a wall in an empty room then I could see how "guns kill people". It is hard to explain my reasoning in words but it all comes down to this. A gun is a weapon controlled by a human being, it does not make its own choices so therefor it is not responsible.
Guns do not kill people. People kill people. I am doing research on school shootings and my answer/solution is not to ban guns. If someone is going to commit a crime or create mass hysteria they will do so if they want to. They do not necessarily need to use a gun, they can use any form of weapon they need. If the intention is there, a person will do it.
As long as Christians are not being disrespectful to the Quran or trying to change any beliefs I believe it is okay. As an agnostic, leaning more atheist, if I touched the Bible to learn more about someones beliefs shouldn't that be okay? I am opening my mind to other cultures and other religions respectfully.
