I too am a little confused. Might be helpful to remember that we will all soon be forgotten whether we reproduce or not.

Unless you chose every death-and-suffering-maximizing option for these absurd trolley problems, in which case you will be remembered for your reign of trolley-derived terror.

I'm a little confused by your rant when they clearly stated having kids as the sacrifice here - which makes a lot more intuitive sense than whatever antinatalist position you're projecting here onto them.

Also, while I'm firmly pro reproduction, this all sounds more than a little judgemental and presumptuous about the motivations of those that chose to not procreate.
