I would like to know an argument that makes abortion a good thing. Make sure to help me follow the train of path you are going through like tell me what you mean by person-hood or conscience so that I don't need to ask it and I can go straight to problems or agreements.
Personally I am not for abortion if this was a perfect world but because it isn't. I am for abortion. Mainly I am for legal abortion because illegal abortion will occur and that would have issues on its own but in a perfect world and now I still take the stance abortion is wrong if wrong is we don't murder humans.
Since I have given my personal stance. You can decide to talk about your argument for abortion preferably outside law and possibly talk about if it was in a perfect world or talk about my position. I would prefer the first but you can do what you want that discusses abortion.
