"Homosexuality, like murder, is a choice."
By legal definition murder is a choice, an act by which one willingly and with forethought, plans and carries out the killing of a human. Other types of homicide (the killing of a human) such as accidentally, during an uncontrollable rage, in self-defense or the defense of another, or as an unforeseen consequence of violent confrontation, are legally assigned lesser degrees of culpability, such as (respectively) negligent or accidental death, killing during temporary or long-term insanity, justifiable homicide in self-defense, or manslaughter. In these latter examples the killer either does not have a choice or is unable to make a rational decision for action.
A large part of the actions involved in homosexual behaviour are no doubt voluntary choices, but other parts are not and are dependant upon other factors over which the individual probably has little control, therefore cannot make a full rational choice.
There are most likely three main "causes" of homosexuality:
1. non-standard positive sexual conditionings during formative years, even into adulthood in some cases, causing sexual orientation to be shifted from the norm of heterosexuality
2. negative sexual conditionings and psychological trauma associated in a person's mind with heterosexual behaviours
3. genetic predisposition
It would be highly unusual for any child to attain adulthood without some conditioning of sexual orientation by parents, sibs, peers, etc. It is a rare adult that can rise above and control the influences and conditionings of his childhood, therefore most sexual orientations are beyond the conscious control of the individual. To bring these conditionings under control requires a maximum sustained effort of self-discovery and actualization of which most people are simply incapable for many reasons. Any effort to do so without active assistance of a highly skilled mental-health professional may cause additional undesirable traumas and conditionings to form.
As for genetic predisposition, remediation of homosexual behaviour caused by genetic predisposition is currently beyond any control by the individual and society in general except by stringent opression of natural urges having very little to do with sex, such as love, affection, and social acceptance. Such opression applied against individuals subject to one, two, or three of the above "causes" would not be ethical in any frame of reference except that of the strict authoritarian, therefore would be counter to ordinary human dignity and freedom.
It can be seen from this short examination above that, for most, there is no choice in one's feelings, likes, dislikes, urges, and sexual orientation. The equating of homosexual behaviour with murder is just plain bullshit.
