"For the Greeks, it was almost a social duty for adult males to take adolescent boys as lovers," Perrottet said.

An oft-repeated libel of the ancient Greeks by the Left. This assertion is made contrary to considerable information that we have documenting that the majority of ancient Greeks lived a normal family life and were not very dissimilar in this regard from modern Americans or Britons.

It happened, but it has been exaggerated. Many Greeks did not engage in this sort of practice, and actively disapproved of it (Pericles comes to mind.) Aristophanes' comedies show characters ridiculing "boylovers" and "effeminate" men.
Oddly enough, it seems to have been more characteristic of "less developed" parts of Greece like Sparta and Boiotia than of Athens.
