You are overextending quite a lot there! Haha!
No one is an AN to that degree at all. That is not AN. I lost my 3000+ word essay on this subject unfortunately (not that I think you would have enjoyed reading it anyway!)
:D
Made a brief summary here:
Antinatalism is based on a two main areas of contention. That is the philosophical problem of nonidentity and application metaphysical valuations.
NONIDENTITY
Firstly, the nonidentity problem is outlined quite simply in ethical terms as how and if we can claim to pass moral judgements that have consequences on persons who do not, as yet, exist. An instance of this would be akin to how we attend our environment with the thought to hand as to how it can effect future generations.
For instance, a culture that prioritises trees, viewing them as sacred perhaps, may also use them to build housing. This would disrupt future generations if they neglected the native forests by effectively destroying them all to build more houses or for use in other sacred ceremonies.
Here we can see a clear neglect of persons who do not yet exist (nonidentity). In contemporary terms this is often equated to how humans have damaged the natural world, thus leaving future generations with future problems to solve they had no direct hand in causing.
Here one antinatalist (AN) argument ensues. This is that we have no right to bring life into the world that will suffer due to none of its own doing. The new life is not responsible for its own coming into being, yet it does come into being. How can this be considered in light of those making the moral decision to have children? Is this morally irresponsible or not? If so to some degree each way, then to what degree and how can we rightly measure this?
Regardless of any personal analysis of this situation we can understand that given certain beliefs about this scenario we can come to see the reasoning behind someone siding with the AN argument.
Some will see justification in talking about the rights of nonidentity persons while others may find this too difficult, or impossible, to hold. The degree to which this can or cannot be justified is tied up in other initial ethics/moral stances (be this deontological, utilitarian, nihilistic, etc.,.).
THE METAPHYSIC OF ASYMMETRY
This perspective is an interesting one regarding moral axiology. Let us assume that measuring such values of human experience can be made in a meaningful way to begin with. This argument puts forward the proposition the probable chance of ‘harm’ and ‘benefit’ (let us use these terms as positive and negative aspects of human experience).
A) If someone (nonidentity) does not come into existence then there is No Harm and No Benefit.
B) If someone does come into existence then Harm is guaranteed (on some level) and so is Benefit (to some degree).
The argument goes as follows …
For A, No Harm is Good and No Benefit is Not Bad.
For B, Harm is Bad and Benefit is Good.
Looking at instance A), not existing is Better than existing because there is an asymmetry between Harm and Benefit, where lack of harm is strove for and peaks in Good in its negation, lack of Benefit is Not Bad and so neutral. No Harm either way.
Looking at instance B), existing is guaranteed to cause Harms and Benefits are not guaranteed to outweigh Harms, even though in some cases they may.
Conclusion: Not existing guarantees No Harm caused. Existing guarantees Harm caused AND cannot guarantee Benefits outweighing guaranteed Harms.
If then the goal is to reduce Harm then it is effectively a gamble when we create new life. The nonidentity person may have a Good OR Bad life, whereas if such a person never came to be no more Harm will be caused to such a person for obvious reasons.
Now to return to the problem of nonidentity …
MORAL RESPONSIBILITY
The question is now how anyone has the moral right to procreate given a belief in reducing Harm following from the principle outlined in the argument of asymmetry?
No one asked to be born (obviously!), but someone did choose to bring life into the world. It is a solid argument for AN to say no to procreation here if they believe in the reduction of Harm as a priority. It is not faulty thinking following that particular line of reasoning with those particular views.
There are numerous other AN arguments that are basically little more than weighing the scales regarding future benefits and detriments to living being (and nonidentity potentials too) that add different themes to the argument. The common ones are Overpopulation, Dystopian World, Inequality, etc.,. These are more or less decoration to the core elements of the AN position I have laid out.
There is certainly weight to argument. Like every other ethical position though it does not present a convincing absolute moral law, but creates dilemmas for those serious about having children who wish to explore the ethical implications of doing so, for their child, other children, their community and surroundings, and all other manner of issues too.
NOTE: There was a another major point I had in the essay regarding ethics in general and Self-interest Vs Common good. Way more involved for that though so omitted it. Hopefully the above helps you see the weight, and use, of the argument presented by the AN position (whether you follow it or not).
