So how do you decide what is right? (I am curious)

Right for what purpose? Without specific context, we only speak in vague generalities.

If one man says it is raining and another says it is not, will you not find only one correct when you look outside…

I must admit I've never seen thought of rain (or any question of observable fact) as a moral choice, only one of sanity.
Isn't that the problem most of us have with medved's fantasies?

How did you come to your belief or dis-belief? How do you know that what is true for ‘you’ is, in fact, true?
