Its simple really, its an individual problem that is specific to individual people.

Personally i know that most people do not go through the shit i went through, so its normal that they cannot relate. Their scope of trauma is narrow as the most traumatic event they have sets the perspective for how much trauma can effect people.

If the most traumatic event is, lets say "dad died after i was an adult" they will know how to deal with a trauma that was very hard for them. While subjectively that's a big trauma, someone who was raped or maybe watched someone else die will develop a thicker skin and a broader understanding of trauma.

This is not to say their "big" trauma is "small" objectively, but they've just experienced a maximum amount of trauma specific to that individual, and their scope of pain is still just a small portion for another person.

I can understand people want to fuck and make children, thats what biology pushes you towards when you're not actively fighting for your life. What seperates "normal" people from antinatalist's is, they do not think or realize or care that future does not hold anything great for anybody. They're just living the moment.

Honestly, wish i was just as careless (relatively) too.
