Because as I read this, you are setting up the argument to be:
Pro choice believes in protecting individual autonomy, as opposed to Pro life, which believes in telling people what to do, because of insert any number of reasons here
This is pretty true of a lot of the pro life apologists and political campaigners, but I feel is a pretty ineffectual argument against the people who truely believe this as an ideology.
The people that truely believe in pro life genuinely don’t see a difference in values about protecting individual autonomy- they believe that’s what they are doing by banning both murder and abortion (something that they don’t differentiate between)
Plenty of these would agree with you that this execution was in fact a murder.
I don’t really have a counter argument that I would like to make, because it’s not and never was my goal to convince you that your opinion was wrong I only intended to critique the way it was made.
However, I am curious where you would personally draw the line on a human infant becoming sentient. This not intended as a trap or an argument- as a conflicted person, your certainty is interesting.
