Hidden meaning of the Equity religion: 

A superior race because they are not Western and white.

Discussion:

Equity Theology teaches that indigenous people are a superior race. They lived at peace with each other and in ecological balance with what the land provided.

In the real world, we know that  indigenous people killed people from other tribes with the same regularity and viciousness that humans have always done. The indigenous people decimated the environment to the maximum amount that their technology would allow just like everyone else has.  

Equity believes the West invaded the land of indigenous people around the world who had been living in peace and in harmony with nature.

It is true that people from the West took over and drove the people out who were living on the land, but this is not something unique to Western culture. Basically every group living on land today took it from another group by driving them away or killing them. This includes all groups labeled indigenous.

Believing that one group of humans is superior to another is like poison in the human soul.
