Anti-Deathism is an off-compass libertarian left, hyper-transhumanist and culturally progressive ideology. This ideology advocates for the abolishment of death and the abolishment of dominance. They want life to have control over all non-life, and to achieve maximum possible freedom for all life. They want every being that ever existed to feel, and if dead, resurrected to feel all unprovoked ruin/end of life they chose to allow/cause, have any ethical therapy needed to be ethical and healthy individuals that reject death, then be integrated into the anarcho-communist, post-gender, ranked approval vote, democratic confederation that prevented all extinction events, created unkillable immortality with the ability of choosing to store and remember memory by choice, and redesigned reality itself to maximize life's benefit. No one being allowed/able to die increases liberty, (read the philosophy section).
Philosophy: Non-suffering is itself an experience, and the concept of experience can't exist in death. You don't see black in death, there's no you to see black, it's the same for non-suffering. Impossibility is irrelevant because our wellbeing in life is the only choice. There is no real reason to die. Disease and war aren't part of the human experience, and neither is death.
