This is a really clear explanation for your feelings about this. I was surprised that me too, although I don't have the same strong reaction to it that you do. I just rolled with it when the first story appeared. It doesn't change Alan's history. He still loved Molly and had a love with her, it's just that, like many other gay men of his day, he lived most of his life in the closet not coming out until recently. DC could have done that story line with any other JSA character, but decide to go with Alan---I am going to guess it was because the Earth 2 Alan had already been established as gay.
