So, gfs, is this a fair summary of some of your understanding?

There are genetic markers that correlate to same-sex orientation. Those markers are created by stress during pregnancy, especially during the first trimester. But sexual behaviour is strictly a choice, independent of orientation.

You explained that genetic markers are changeable. Do you believe that in successful re-orientation therapy the genetic pattern is changed back to "straight" ?

Going back to a video that you linked quite some time ago: do you believe that being hugged and pounding on upholstered furniture can correct flaws in a person's genetic makeup?
