1) Our scenario starts with birth. The boy (for example) who one day may go on to struggle with homosexuality is born with certain features that are somewhat more common among homosexuals than in the population at large. Some of these traits might be inherited (genetic), while others might have been caused by the “intrauterine environment” (hormones). What this means is that a youngster without these traits will be somewhat less likely to become homosexual later than someone with them.
What are these traits? If we could identify them precisely, many of them would turn out to be gifts rather than “problems,” for example a “sensitive” disposition, a strong creative drive, a keen aesthetic sense. Some of these, such as greater sensitivity, could be related to – or even the same as – physiological traits that also cause trouble, such as a greater-than-average anxiety response to any given stimulus.
No one knows with certainty just what these heritable characteristics are; at present we only have hints. Were we free to study homosexuality properly (uninfluenced by political agendas) we would certainly soon clarify these factors – just as we are doing in less contentious areas. In any case, there is absolutely no evidence whatsoever that the behavior “homosexuality” is itself directly inherited.
