Describing things as sin has absolutely no meaning to me. Morality for me is about avoiding and where possible preventing unnecessary suffering, and while I accept this is a subjective view, it at least has the merit of treating everyone the same, regardless of their beliefs, or the lack thereof. Don't like abortion, don't have one, don't like unmarried sex or masturbation, don't do it, don't like blasphemy or vituperation, don't do it, don't like gay people, keep it to yourself. just let others live their lives, and you live yours.
The only meaning sin has to me sin the context of the religion I am addressing. I actually consider morality, absolute right and wrong to be a religious concept, which is what is considered good and evil varies so much between religions. And I don't think that many non believers in the west realise that that very concept of morality is an inheritance of Abrahamic tradition. So in a way they carry that religious idea with them. In the east, that concept, in most cases, is non existent (as far as I have researched).
The way I approach it is: What is the goal we want to achieve? What actions are best suited to attaining that goal and what actions undermine that goal? This renders good and evil to be matters of perspective.
I would say that the goal that most of us aim for is a harmonious society that maximizes well being among us all. And your point caters to that goal.
