Dedicated to CM and Stacy, thanks for rectifying my views.
"but if you believe that it's okay to use force to prevent people from murdering others, then the same reasoning should apply to using force to prevent births (because birth entails death, plus a whole lot of other shit, so in most cases it's actually worse than murdering someone" - CM
It is 2110. Not everyone is in favour of antinatalism yet, but thankfully, the bulk of politicians constituting every world government are. Even with fervent opposition from several pronatalist pressure groups, the Last Law is passed on Earth and on Mars alike by every major world power: sterilising chemicals are to be introduced into the water supplies, and into the commercial food products available. People have no say in this matter at all, just as perhaps, the politicians would say, their children have no say in the matter of being born. Riots break out, terrorists detonate explosives under parliament buildings - but not for their own sakes, for the sake, they think, of the entire human race. The politicians believe however, that what they are doing is also for this sake. Who is right?
As you may have seen from the comments on this, my views have taken a complete U-turn on this matter. I used to believe that consent was King, but I didn't particularly understand why. The thing is, people do not give consent for the police to stop them when they commit some wrongdoing - the point is, they don't have to, because they SHOULD NOT have those rights. For consent to matter you must deprive someone of something they are entitled to, and as I learnt from Stacy recently, no one should be entitled to breed. If you sterilise someone against their consent the only harm you are doing is the harm of wasting some of their leisure time. No one has the right to bring a child into this world, for the simple reason that this action, as we antinatalists have already established, is completely and utterly immoral. You do not have my consent to stop me punching you in the face. If you do it, you will be violating my rights! That is exactly how I would have thought about such an action as I have described in the above scenario - I just had a knee-jerk response to the whole thing, which was, in hindsight, almost eerily similar to my previous knee-jerk response to abortion. "It's just wrong", comes to mind.
However, though I would definitely support, now, the above scene, I wouldn't exactly think it the best thing to do, anyway. It's a morally justifiable action, yes. But it isn't really a smart action - better wait until antinatalism gets more popular before you do something like that. Or else bloodshed could be on your hands.
