The truth is that there are no such links, TP. The studies you refer to suggest that homosexual orientation may be genetic. They do not suggest in any way that homosexual behavior is anything but a choice. If you notice my post, I was very specific about what I was referring to.
People do have a choice about who they are sexually active with. That is not forced on anyone but rape victims, and I assume you weren't talking about rape. Attraction may be genetic, or partially genetic. That's a different issue.
