For an atheist, it's all life so ending the process at any point is technically death. Every sperm is sacred, so to speak.
For a Jew or Christian though, the Bible doesn't consider the unborn to be human until they are birthed. Instead they are considered potentially human. Since it is not human, killing it isn't considered murder.
Evangelicals wrongly believe their Bible considers the unborn to be human, thus their anti-abortion stance. If you look back to the 1960's, Evangelicals were not anti-abortion. That changed in the 1970's and here we are today.
This isn't true.
A fetus in the early stages of development is not alive in the regular sense because it is incapable of independent survival and lacks the requisite organs to sustain itself, experience pain etc.
Most elderly people including yourself some years from now will not be "self-sustainable". You will need help to move around, you will need medications to survive and all sorts of help.
There is a congenital disorder which makes you insensitive to pain. Does that make you not human?
It is a rather dumb argument.
2) Measure the vital signs of the organism. You will confirm that it is alive.
3) Try the same with other mammals.
Please go ahead and try to falsify this. Have fun.
