Premises:
0. We are in the pre-eugenics era.
1. You allow for a world without choice.
2. You have no good evidence to think your choice will be selected.
3. You don't like people taking away your choice (in this case people implementing systems like idiocracy).
0. Yes, the concepts are still in the process of normalizing.
1. Not immediately, but rather through a series of steps. Choice must be earned, rather than be accepted as a divine right of one's birth.
2. I have factored it's potential and odds, while what you ask for would require me to be capable of divination.
3. What I do and don't like as an individual is irrelevant to the debate itself, especially when it comes to abortion rights being the first of many important steps. I've otherwise already argued against the evils of abortion, both in the interest of the advancement of and independent of the Fascist Eugenics Agenda.
Okay, let me re-phrase the premises to account for what you said:
0. We are in the pre-eugenics era.
1. You allow for a world without choice (eventually).
2. To the best of your knowledge, you have no good evidence to think your choice will be selected.
3. You don't like people taking away your choice (in this case people implementing systems like idiocracy).
The argument is still virtually identical, applies, and is unchanged. Are you fine with these premises? They should address your concerns.
Regarding third point: Why do you think viewpoints do not matter? What you do and don't like as an individual has everything to do with the debate, because we're talking about subjective views. We will have an entirely different debate if you believe that genocide is good and medical care is bad, than if you believed the opposite.
I would argue that the only way we can have a debate over viewpoints is that we agree to certain premises and subjective views. Otherwise the best we can do is list cons and pros and hope that whoever is reading agrees with us. There will be no logical pathway to demonstrate the fallacy of the logic of the other person, if subjective views and personal preferences do not count in a debate about an entirely subjective viewpoint. The only way I can possibly show someone is wrong is by adopting their framework.
I'm fully happy with you being able to "retract" and "modify" your opinions, given that you acknowledge doing so transparently. For example, if you now want to change the 3rd premise by changing your opinion on the subject-matter, I'll happily go along with it.
That's all fine and good, but you haven't given any reason to believe that Pro-Choice is better.
My starting point is that unless there are good reasons to restrict individual freedoms, we should allow for individual freedoms. So I don't need to give reasons to justify not restricting individual freedom. If that was the starting point, we'd be completely screwed regarding everything. It would be like stating that I need to prove that there is no God to counter an argument for God.
Your only argument is only that it might fail,
No; I said that according to your own premises it will probably fail, and we're talking about the potential destruction of the human society. You said you don't like idiocracy. Therefore, it follows that you're working against yourself.
The crux of the argument is: By advocating for no free choice, according to your own premises, you are advocating for people to take away your will, against your will.
If you do not like me applying it to you specifically, you can replace the argument with:
"By advocating for no free choice, the person is advocating for people to take away their will, against their will."
so in conclusion you see Nihilism as the better alternative?
Could you elaborate? I don't understand what nihilism has to do with my viewpoint? I'm merely pointing out that your argument is self-contradictory in that it is working against the person utilizing the argument. To my knowledge, I am not adopting a nihilistic viewpoint, but I'm happy to be proven wrong.
You have yet to actually argue why your idea is better,
I don't believe I do, for reasons stated above.
As I stated before, either we stay with Pro-Choice and accept that we've failed
But you're not addressing my argument. Do you agree or disagree with it? Or do you agree with it but think it's irrelevant because all pro-choice possibilities for your eugenics plan will cause certain ruin? If that was your stance all along, then I'll be happy to debate it, although I think it's a much more difficult stance to argue for than what you've debated thus far.
