frenchcda, indeed OOT, but interesting nonetheless.
In a sense, BBM is timeless, in that it did not seem to reference any of the touchstones in recent Gay history. I think it was partly because of the setting: rural Wyoming, so far from the gay efloresence of the Cities and the life lived on edge. It is partly intentional: to make the story resonate more universally -- make it timeless and boundless.
This said, it is interesting that the period corresponding to Jack's death falls pat on the start of the great Epidemic. Anyone who has seen friends and acquaintances swept away will capture some nuance of a correspondence.
Whether the symbolism is there or not, I think, in the end, the love and death of Jack Twist transcends even these defining moments -- so raw and affecting even to us today.
Jack Twist lived and died under one defining love. The exact circumstances surrounding this death or any period symbolism that it may represent pales in comparison to that love. Had he died of AIDS, it would not have changed the substance of what defined him as a character in BBM.
In the end, there is only one reference. There is only one touchstone. There is only one defining entity.
His name is Ennis Del Mar.
