I have stated on the Randee post a lot of information that I see no need to repeat here. In fact a lot of evidence, so I would refer you to that post to review that information.

In short though the majority of what we do is by choice.

To put anything, even as to lifestyle, into the category of predisposition, which is what it means for something to be genetically encoded, is to deny choice.

From a spiritual reference, since the beginning we have always had the freedom to choose our behaviors and habits and though we be faced with any temptation or feeling, it is still a choice on how we act on it.

Now you made reference to some of those who turn from the alternative lifestyle, again by choice, not seeming any happier. That is also to say that they were not happier the other way as well, thus there was something weighing on them and if that is the case then when one is faced with such things, as all of us here understand being through the emotional turmoil of divorce, it is our choice to either stay stuck in it, or change our way of thinking. I believe that this is most likely what you observed, is that if they did not seem any happier, then they may have very well been stuck.

Now the other problem with predisposition is that there is not enough known about the human genome at present so no real hard evidence exists in this arena, only theories and possibilities which are a far cry from fact.

A problem that is all to common in todays society is that theory and possibility are being bought into as fact and evidence, and this can be a dangerous thing, and way of thinking as well.
