Well, please don't repeat this to him because what I'm about to say will only encourage him. It does not come from that same bigoted place that he and so many others are coming from. But he is partially correct in that what we are is primarily in our genetics, like alcoholism, cancer predispositions, hair color, general temperament, intelligence, race, height, etc. But it has none of that negative flavor that he and the other bigots are trying to put on it.
I believe that we humans are primarily wired to be bisexual and most people just end up on a side, with the majority on the hetero side and a minority on the homo or bi "side," with lots of variation in the in-between spaces due to Hippocampal structures, culture and lots of other things we don't even know about yet. Some people even grow up to be asexual, sometimes early, sometimes later in life. All types of people, all types of sexuality.
The bigots not only have a side, but they actively defend it as if it's the only way, disregarding the scientific aspects of human variation. Yes, there are homosexual bigots, too.
I'm not saying people consciously pick a side (although I bet there are some who do!). I am saying that people do drift to one side, predisposed by genetics, developed over a childhood, through adolescence, into adulthood. And I know that it keeps evolving as a person grows older.
We westerners always want to make these things black or white, but they're not. It's not even the Kinsey scale, frozen at a number "I'm a 4." Human sexuality is so much deeper and more varied, changing with age and situation and personal growth over a lifetime.
Rick Perry, what a sad, sad example. Not a good leader.
“We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another; unevenly. We grow partially. We are relative. We are mature in one realm, childish in another. The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made up of layers, cells, constellations.”
