When publicly discussing spirituality, distinguish thought of the material world, what we directly experience, from the spiritual interpretations beyond it. Organize each spiritual idea into agnostic, non-theistic, and theistic.
Situational ethics, like Just War Theory, can be brought down to your life. When you cannot turn the other cheek, strive for a response that is proportionate and never exceeds the harm done.
Religion is not automatically harmful. It can become dangerous when a specific private speculation is promoted as empirically or rationally true. Belief without evidence must remain speculative, not wrong, just not proven.
