The majority of the people on this planet do not look to the same God you do to know that they are right or wrong.
You judge everything by what you believe that your version of God said, wants, and expects.
Others have a right to set their own standards according to what they believe or do not believe. You have a right to believe as you will but your rights stop completely just short of imposing them on others. That is why we have laws.
Living in a christian theocracy would be no better than living in an islamic theocracy. I refuse to be ruled by religious zealots no matter what flavor they are.
I will point out to you that if any deity exists at all, then it does matter.
Your post assumes atheism as a given.
You can’t get there any other way.
For you to have any intellectual merit here at all, you will need to prove the non existence of a creator God. Even agnosticism is not enough here. You have attempted to imply that categorically there can be no being with the authority to impose standards on its creation.
