You can date homophobia from the Pious Forgery of Hilkiah in chapters 22 and 23 of Second Kings. Hilkiah was the high-priest who had the King of Judah assassinated and led his six year old son Josiah away by the hand, married his own daughter to the young king, and brainwashed his son-in-law the new King Josiah into believing the pious forgery that Hilkiah wrote and hid in a hollow column or pillar in the Temple, planted for the workmen he himself ordered to find, and attributed to Moses. Homophobia is Hilkiah's lie which infected Judaism, causing the murders of the Temple catamites under Josiah's "Josiannic Reforms" in 627 BC and the Destruction of the Temple along with the invasion of Judah by its neighbours, as well as an infection spread into both Christianity and Islam. Jesus never said anything homophobic. You cannot date homophobia any earlier than the Josiannic Reforms of 627 BC or anywhere else as a "human thing" before any other human society came into contact with the original influence spreading out from Hilkiah. For example, in 627 BC, Japan believed in Amaterasu who newly founded their imperial family, and established a tradition among the Samurai of male on male mentorship amongst the Samurai which lasted right up until the 1600s when Catholicism, carrying Hilkiah's invasive poison, destroyed that aspect of the ancient Samurai tradition.
