It's normalizing a condition of mental illness, more precisely, an identity crisis that's the problem.
Your examples are my examples. There is no rationalization that can fit homosexuality into the paradigms of physical existence on Earth without treating it as an illness.
Sir,
You specifically framed the debate by stating that no society tolerated this conduct. Well, schizophrenia, mania, depression, etc all were present in societies, but they were not enshrined in the cultural norms of major civilizations.
Thus, whatever you may think of homosexuality or its attendant sexual deviations from heterosexuality, there HAVE BEEN societies in which homosexual conduct was tolerated and even encouraged.
Tokugawa Japan could have continued had the West not existed and its fall had little or nothing to do with the sexual mores of the nobles.
