Can you not be a person at one second and magically become one the other?
You've completely missed my point.
Why can you not join the military at 17 years, 364 days, 23 hours, 59 minutes, but you can at 18 years?
Why can you not buy alcohol at 20 years, 364 days, 23 hours, 59 minutes, but you can at 21 years?
You have to apply an arbitrary cut off to a continuous process (time), so you are always left with situations like this.
Now, if you read my previous post, cortex development necessary for consciousness takes place at 24-26 weeks. So no, a fetus obviously isn't unconscious at 23 weeks, 6 days, 23 hours, and 59 minutes, and conscious at 24 weeks. It is a gradual process over the space of 2 weeks. If you make the cut off 24 weeks, i.e. before that process has begun, then you can be sure the fetus is not conscious since it does not have a cortex.
Alcohol arbitrary cut off dates don't end lives. Abortions do.
You can't apply an arbitrary cut off date to a fetus, because nothing can not be a person at one second, and magically become one the next.
It is a gradual process over the space of 2 weeks. If you make the cut off 24 weeks, i.e. before that process has begun, then you can be sure the fetus is not conscious since it does not have a cortex.
The point is still the same, there is a second in between the fetus being a person and the fetus not being a person. There is a second where you have to draw the line whether the cortex is developed enough or whether it isn't. A literal second between hundreds of fetuses and you'd have to draw the line to which can be destroyed and which can't and thousands and thousands only differ in seconds of age.
There is a second during that week where you make the cut.
