This is an excerpt from a larger response to a local author, to which the fuller response and more context, see here.
Very bluntly and plainly, Socrates was not “gay,” per se. He was a pedophile, most pedophiles in Grecian days slept with young boys, a homosexual act. Pedophilia became common practice for the well-ta-do, and it took the Judeo-Christian worldview to shake this “habit” from the world in outlawing such actions. “Many men in Ancient Greece had relations with young teens,” however, “being outright gay and having an equal relationship with a same-sex partner was not something that was socially approved of at all.” Plato speaks to the “mean state” that creates the best “by far the safest and most moderate” a society should promote to enhance its quality of life. One should take note that even Plato’s detractor in the end agrees:
Now, what lives are they, and how many in which, having searched out and beheld the objects of will and desire and their opposites, and making of them a law, choosing, I say, the dear and the pleasant and the best and noblest, a man may live in the happiest way possible…
Speaking generally, our glory is to follow the better and improve the inferior, which is susceptible of improvement, as far as this is possible. And of all human possessions, the soul is by nature most inclined to avoid the evil, and track out and find the chief good; which when a man has found, he should take up his abode with it during the remainder of his life…. every one will perceive, comes the honour of the body in natural order. Having determined this, we have next to consider that there is a natural honour of the body, and that of honours some are true and some are counterfeit…. but the mean states of all these habits are by far the safest and most moderate;
…but they will not wholly extirpate [root out]the unnatural loves which have been the destruction of states; and against this evil what remedy can be devised?…
Either men may learn to abstain wholly from any loves, natural or unnatural, except of their wedded wives; or, at least, they may give up unnatural loves; or, if detected, they shall be punished with loss of citizenship, as aliens from the state in their morals. ‘I entirely agree with you,’ said Megillus,…

Another piece to the puzzle comes from an excellent apologetic about this very subject. In it we find this:
Aeschines (390-314? BC), in his work Against Timarchus, acknowledged that there were laws on the books that prohibited sexual harassment or assault of young boys.5
1. He further records that Greek law prohibited male prostitutes from holding office in civic affairs, or participating in religious observances.
2. He recognized that laws that regulate moral conduct are the best means of establishing and maintaining an orderly society.
3. This work indicates that there were laws prohibiting these things, and that the punishment was fine or death, depending on the severity of the offense.
So, even in Greece, you had a behavior that was rejected as unnatural, and never accepted in a moral category as “the norm.” So nothing John cites or references would support Prop 8 or the peoples will in California to keep marriage what it has been, a relation between a man and woman (specifically, one man and one woman).
