Firth(who said he was going to stop this...but won't..or can't): "There is general agreement among geneticists that sexual orientation IS genetic, but the genes do not always express themselves, which is the nature of recessive genes."

But receptors DO manifest their activity and their influence over behavior, but they CAN be 're-trained'....and that is MORE than a 'general agreement' with psychologists, geneticists, rehab centers, religious folks, and politicians.....how do you think they get you to leave common sense, and make emotional issues out of thin air...then exploit their 'followers'???
It seems now that TWO of your influential 'studies' and your learned friends have stated as much....but then look the other way, and gloss over it, just to push that it is all 'genetic'...when it is clearly not.
Is a cup, a cup of tea, till you put tea in it???
Hardwired genetics can determine a male or female, right or left handedness, blond or brunette, two arms and two legs...but what you do with all those things is dependent on behavior. The notion that 'There's a woman trapped in this (male) body', is complete and utter nonsense...HOWEVER, how one INTERPRETS certain sensitivities, then attributes those 'feelings', is just a matter of INTERPRETATION and PERCEPTION of how and what someone THINKS is feminine(or masculine). Receptors influence what and how you CHOOSE to satisfy the urges of the receptors needs. Genetics will give one a REPRODUCTIVE SYSTEM..FOR REPRODUCTION or the species..any species...one's fantasies of how to manifest sexual(reproductive) urges, again is NOT necessarily attributed to genes....however, the 'equipment' to reproduce is.
To understand the role of receptors, and how the 'create needs' emotional or otherwise, is on a video link that I already provided on here. Maybe you should re-visit it....and BTW, before anyone begins to criticize the video, take a hard look at the people behind it's production and writing....monsters in their fields!...and carry more weight than the 'studies' you put up!
