If you want to discuss this issue with me please read my comments more carefully. I said no such thing.
Sorry, 400 causes. I added an extra zero.
Just click on Scripter's name up this thread and look at his links. I just don't have time to get them for you. He's got zillions of articles, arranged by topic, and you can read for hours about the causes of homosexuality. They may be unknown to you, but they are not unknown to others.
little_jeremiah was merely paraphrasing as to "number of causes of homosexuality" for the sake of discussion and I don't read from what he wrote that he's alleging to quote you literally, just saying, again to paraphrase BOTH of you, of the many, alleged causes of homosexuality...
To my read, I didn't find what little_jeremiah wrote to be in any way problematic to what you wrote, earlier, here.
You opined that to your view, the "causes" of homosexuality were nearly if not completely unaddressable, and mentioned the many viruses that cause the "common cold" to be as equally mystifying in difficulty to identify as any one cause, any one infectious agent.
Homosexuality, you opined, to my read, was similarly difficult to prove as to any one cause, referring to your example of the many different viruses that cause the common cold, to repeat this in another fasion.
And, actually, although homosexuality as behavior IS difficult about which to identify any one cause, I agree and so does most of medical science but it's not a "one cause" issue as most behavioral aberrations are. They are caused/created by SYNDROMES of behaviors, a syndrome meaning a myriad of conditions combining learned options from a cultural and familial environment.
It's easily confused and has been in general as to the biological abnormality of chromosome variations in some individuals which can and does often result in physical abnormalities in individuals.
Yet, those are a different area of study altogether from homosexuality.
Not that you've mentioned that here but that I thought I'd now include that since earlier some comments were pursuing the "some people are born with conflicting gender" issue.
That does not mean that homosexuality is immutable, that a person is born with homosexuality. Chromosomal variations and aberrations are not the cause of homosexuality and someone born with chromosomal aberrations/abnormalities is not compelled to be homosexual when functioning from their gender, such as it may be.
Homosexuality is another area of behavior, is the point, apart and distinct from chromosomal abnormalities, compared with the normal chromosomal inheritance of male and female gendered individuals.
No "gay gene" there!
There are, also, a myriad of reasons why people learn to act impulsively. It's not a case of being impossible to define but of the fact that behaviors are learned, not inherited.
We all inherit potential. It's developed differently, affected differently and greatly influenced by our environment.
