“...you will be going against most of the people on this planet”

yes, and that includes the people who profess the Christian religion.

Jesus Christ: “Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent.”

John 17:3

Christian religion: “Whosoever will be saved , before all things it is necessary that he hold the Catholic Faith. Which Faith except everyone do keep whole and undefiled, without doubt he shall perish everlastingly.

And the Catholic Faith is this: That we worship one God in Trinity, and Trinity in Unity”
