Having kids is always an act of selfishness. You don’t do it because you are trying to ‘gift’ life to the child. You do it because you think it will make you happy. Look at your reasons.
“me and my partner have wanted children since we were children” There’s your reason. You have the biological imperative. You want your genetics to continue.
" if a life is not worth living it must be an absolutely horrific and torterous experience." That’s life. ‘Worth’ is purely subjective. Objectively, life is worthless. If you have the right genetics and circumstances, you can ignore this fact, but it’s always there.
“If all of us liberal and educated folks stop having kids what will the world look like?” This is just the ideological version of the biological imperative, the idea of ‘my ideas must be passed down’ instead of ‘my genes.’ But it is based on faulty assumptions. It assumes your kids wouldn’t become fascists just because you aren’t. It assumes the children of members of a political party will automatically join the same one when they grow up. Why would you assume this? Do you have the same views as your parents? Grandparents?
If you want to have your kids, go ahead, but don’t delude yourself that it’s your gift to the leftist cause or to the child. It’s a way to scratch your biological itch to be a parent, just as much as masturbation and sex.
What about a 360deg camera, where the target person is yourself, and anyone else captured is merely incidental/background?
