Thank you very much for your sober reply. And while we are it, I take of my hat for your background.
If we leave behind your academic and very insightful thoughts just for a moment, and be less clinical in your observations. And rather just think of them as human beings with a heavier luggage than the average normal person would carry. Lets forget about the selection and the strong mans evolution, and just accept that us humans are such a complex fusion of cells that happen to live on a planet that just happen to be on the magic distance from our sun, so all the life we know of can live.
A life is what we have. And thank God I was born in to a civilized world where I had a chance to grow up and be curious about the rest of the world. I have an aunt who is 70 years old who has been happily married for 50 years with the same man. They don´t have children and they choose not to have them. It was a decision they both took, but they love children nonless. When they were still young, people were looking at them with sceptic eyes and thought of them as odd, and my grand parents were sad becuase of this. But time flew by and with each decade, people were less judgemental and today you don´t have anyone questioning their choice of life. And you will often hear the jealousy and the achievement they have had from life without children.
I don´t know about the clinical studies that has been made of the happiness of those who has taken the way of hormones. Maybe you are right, maybe they still feel awful after their transformation. But who are we to judge their choise to do so? I acknowledge they are not part of the religious curriculum and therefore not accepted as human beings, but I happen to believe that if your religion dictate to much of your daily life, the gerneral knowledge will also be a distant grail of wisdom.
Some people mention reproduction. What about adoption? Are gay people excluded from that list, because they can´t have the child the normal way? We have many gay couples in the north that have children. 10 years ago the majority would still raise your eyebrows if that happened, but today they are the minority. As with technology, the humanism is also in rapid evolution.
People should think more outside of the psychology box and the norm that is now will be a distant farewell in a short lapse of time.
