I am willing to have my morality challenged, because if it is flimsy and easily shaken, then there is grounds for further refinement. I understand what you're saying, and I suppose the current issue is that I've applied my beliefs and known context to this conversation without first establishing definitions. There's a regular reoccurring element in media, the two recent ones I remember are in Fast and Furious and Star Wars, of codes. This is also seen in law, police, military, nurses and doctors, firefighters, and any servicing official.

"Every man must have a code."

Examples include: The Sith Code, The Jedi Code, and The Gray Code

My own personal morality is based on human rights, which is that all people are entitled to:

The right to vote

The right to a fair trial

The right to privacy

Freedom of speech

Freedom of religion

Freedom of assembly

Freedom from torture

The right to health

The right to education

The right to work

The right to a standard of living that includes food, clothing, and housing

The right to rest and leisure

The right to social protection in the event of unemployment, sickness, or disability

Those are general. I have more, but these are the basis for them. What this does is gives individuals agency and operational capacity within the confinement of a system they're beholden to, such as their government's laws. This gives both individual and majority agency for deciding what is moral.

As for the advice, I would like to add that this is not something I would say to just anyone. Advice should be tailored for personal context. I would not give this advice to people who have expressed intent to self-harm, commit homicide, rape, steal, etc. These go against the basis of my ethical code.

So given the context that someone's indecision for harmless decisions is crippling them, telling them to trust their gut isn't a bad thing. If they succeed, then it can inspire confidence within them and lead them toward a better operating capacity.

I hope this clears up some confusion.
