It was not accepted. You were put to death if you were caught. The only place that slightly accepted homosexuality was Athens and they got what they deserved. it was strictly forbidden.
The only reason we have this narrative that the "Greeks were gay" is because of one faggot historian professor who was woke before it was cool and decided to rewrite history. He didn't like masculinity at all and wanted to emasculate them. Yes he was also a faggot. It was a flat out lie. Always was. Universities just praised it because they love Gay Dick. Historians accepted it only because academia is a pozzed, incestual and terrible place.
"I think I ought to say something also about intimacy with boys, since this matter also has a bearing on education. In other Greek states, for instance among the Boeotians, man and boy live together, like married people;5 elsewhere, among the Eleians, for example, consent is won by means of favours. Some, on the other hand, entirely forbid suitors to talk with boys. The customs instituted by Lycurgus were opposed to all of these. If someone, being himself an honest man, admired a boy's soul and tried to make of him an ideal friend without reproach and to associate with him, he approved, and believed in the excellence of this kind of training. But if it was clear that the attraction lay in the boy's outward beauty, he banned the connexion as an abomination; and thus he caused lovers to abstain from boys no less than parents abstain from sexual intercourse with their children and brothers and sisters with each other. I am not surprised, however, that people refuse to believe this. For in many states the laws are not opposed to the indulgence of these appetites."
-Xenophon, Constitution of the Lacedaemonians
The Greeks were so much into boy fucking that they outright REFUSED to believe the Spartans didn't bugger boys like they did. Sorry nigger, you're WRONG. The heathens were helplessly given over to their unnatural passions, being, as they were, severed from the divine light by their demonic idol-worship, until the True Religion finally put out that fire once and for all. Sexual orientations are a meme, and being gay is a choice.
