Okay, so as it stands, we have a difference in beliefs. When I choose to say something becomes alive, human, or person, is different that what you believe. Do you have the right to impose your belief on me? Again, these are not medical or scientific facts that we’re debating. It is a definition based on morals and values, and what ever else you use to arrive at your conclusions.
There are lots of people with lots of wrong beliefs, and they will never be changed. I think your beliefs are as stupid and ignorant as you think mine are.
When dealing with a system of beliefs, one could argue that the 80 years someone is on Earth is pale in comparison to the eternity they will burn in hell-fire, and it becomes their duty to force beliefs on a sinner to make sure they go to heaven. At what point are you forcing your opinion on me, and is that right?
If you want to point to slavery as a failed system of beliefs, how is the mother not a slave?
And as an aside, a mother has the right to decide drastic medical procedures on her newborn such as open-heart surgery that could have an extremely high fatality rate. Should she have the right to decide such things?
