I'm probably closest to absurdism- seeing as it does all seem absurd! I don't believe in a fixed meaning to life but, I think we can generate and believe in our own meanings. I used to feel like I had a purpose and, it made life easier. I think it's a good coping mechanism to feel like we have a purpose.
I think we ought to be given the fundamental right to leave this life (so long as we can reason and we fully understand the choice.)
The problem as I see it is- as soon as we're born, our lives become interwoven in a whole bunch of codependent relationships. So- whatever we do or, don't do, can deeply affect others.
It's one thing to choose to be in a co dependent relationship and then feel trapped and beholden to another. It's another to just dump someone in it and expect them to comply. That isn't fair but, that's just the reality of our lives.
There are also things the majority of us will have to comply to or else, face horrible consequences. Most of us will have to work in order to pay for our lives. There are also so many dangers in this world that we simply can't be protected from.
To me, that adds up to a very unfair and totally uncertain environment to enlist a child in so- I hold antinatilist beliefs also.
