Sin lies only in hurting other people unnecessarily. All other "sins" are invented nonsense. (Hurting yourself is not sinful -- just stupid).Robert A. Heinlein, Time Enough for Love, 1973
Some of Heinlin’s earlier works remain among my all-time favorites. It was, indeed, sad to read Heinlein’s last several works, and to observe the obvious progressive deterioration of a once-fine mind...
You have no right to define *sin*. That’s a religious term and only people who are religious or theists get to define their terms.
Just like evos say that only scientists can define *theory* as scientists use it and that anyone else’s attempts to define theory in that way is invalid.
So I propose that, not being qualified to define religious terms, by default your definition of *sin* is invalid.
That quoting of Heinlein is lightweight, beyond goofy and into bizarre yote, about about as bizarre as some of your other fetishes.
