I'm not an efilist, as I view the world quite neutrally. I think negativity and positivity in general are human concepts. And outside of the human scope of rationalization, there is no such thing as good or bad. Things are just the way they are.
However, I'm an anti-natalist because I believe that bringing another conscious human being into this society full of treacherous bastards is an inherently selfish act, due to the human's inherent ability to philosophize and to pander deeply about controversial, dark topics. It's just more suffering for more people.
