Darkspilver, thank you for sharing this reference.
This quote here really addresses my question:
"The Bible does not comment on the biology of homosexuality, although it acknowledges that some human traits are deeply ingrained."
Clearly, the WTBTS is avoiding directly commenting on the reality of biology in reference to human sexuality as elucidated by science and abundant empirical data. They hide behind this bit of theological subterfuge and obfuscation: "Since the Bible doesn't comment on it, neither will we."
