A world without Abrahamism.

The world would have been far better off if Abrahamic faiths were never invented.
Without Judaism, Nazism and Marxism would not exist either.

However Abrahamic faiths were the inevitable result of Zoroastrianism.
And Zoroastrianism was the inevitable result of a certain dualism already found in Canaanite polytheism.

So really the problem is the races that are native to the near east.
They had an error in their thinking.
From this, they infected all other races when they invented the globalist versions of their faiths in the form of Christianity, Mohammedanism and communism.

If everyone had remained pagan, there might not have been utopia without war, however, paganism itself guards against utopianism because there is no "end to history" as we find in Zoroastrianism, Abrahamism and leftism.

If everyone had remained pagan, there would have been less the problem of "convert everyone to this religion" because in paganism generally is acknowledged that truth is in different forms shown by and to different peoples.

Pagans were eager to adopt foreign religious gods in addition to their own.
This is very far from Abrahamic monotheism.
Abrahamism's intolerance is also mirrored in leftism, nationalism, feminism, environmentalism; which sees history as a battle between the unconverted and the converted.
