As I have said, it appears that homosexual traits are heritable but not genetic. They fade out if a society is disciplined. The Torah teaches that it takes three to four generations. Remember: it was written by herders who breed sheep. Gay sheep are eaten as soon as they are discovered before they can do any more damage.
I’m not sure I understand you here. Your use of the word heritable causes me to thing hereditary, but then you state not genetic. I don’t understand how that can coincide.
