@sim @mangeurdenuage The world does not always conform to the way we desire things to be.  Sometimes this is a social thing, and we can affect the change we wish to see.  But things like biology, chemisty, the stuff of stars from which we are forged, are not so easily mutable as we want to believe.  We want to salvage some feeling of importance, some feeling that we are in control of ourselves and our destinies, by believing we can arbitrarialy determine what we are or whom.  When we found that the Earth was not the center of all things, we reassured ourselves that the Sun was, and well, we were close enough.  And when the sun was disproven to be the center of the universe, we then reasoned, well the milky way was, and that was close enough.  Likewise, in the light of the startling realization that sometimes we do not feel in control of whom we are, we turn to these therapies as a means to try to salvage our damaged pride.
