If I insisted they leave during a blizzard and they died of exposure I don't think that is murder.Yes because you can’t kill someone on a whim. In this scenario, 99% of the time you’d be doing something to invite a person (with no ill intent) to your house, and if you then asked them to “leave”, and your method of removal would be to kill them, scrape them up with a shovel, and put them in the trash on the side of the road. Well that’s not very legal is it? If you did something with the chance of luring someone into your house, then you killed them, well that would be called murder.
Not a very good analogy but my point is that if a mother's rights conflict with the rights of a single cell/fertilized egg, I'll side with the human being that can think and feel.
