My values come from me, and my experiences as I live. It may sound a bit off of my "type" but I do not believe that the "traditional" values of any society have any inherent validity to them. I believe in the individual - their right to experience life in their own way, and to take responsibility for their own actions. This is what I value in myself, and in others as well. The fact that I fight for everyone's ability to make their own decisions and not follow is counterbalanced by my (admittedly almost fanatical) insistence that they take responsibility for their own actions and not attempt to pass the consequences off to someone (or something) else.
So to address the OP, I don't get my values from others, or society as a whole. Perhaps because I'm expected to (as an upstanding, conservative member of that same society) would be a reason for the split between reality and theory.
