Humans are doomed because collectively we are not capable of seeing the simple solution of requiring human fairness as our #1 priority. Unfairness of humans must be our #1 concern. Unfairness is the only immorality. Instead of this simplicity to guide our behavior, concerns and policy we use religion or some other imaginary construct.
The results in an impossibility to unify everyone. It results in powerful people being able to subjugate the less powerful even though this is obvious human unfairness. We are in a life-or-death struggle to gain power and being unfair is the fastest easiest way to gain power over others.
Human fairness for everyone and from everyone will result in everyone protecting everyone from human unfairness. Humans will not seek power over others. Humans will seek a world of human fairness.
How can we get the religions and political rulers to make human fairness the #1 priority? How can we get everyone to unify toward this cause of human fairness.
People are being motivated by a thousand different causes that will not ever unify the world.
