i like the way you put it: it's interesting to delve deeper. but it's not necessarily relevent as far as the artist's deliberate body of work is concerned.
i feel that we should make every effort to view the artist's work separately. that's not to say that our emotion wont sway us, and that i guess is the risk the artist takes when he or she is careless or less than meticulous about keeping personal information private.
you're not wrong. there's no wrong. i like your thoughts.
