The article correctly points out that the Greeks didn't have a concept of "homosexuality" in the sense used today [1], and that the more accurate word for the Greek practice is "pederasty". [2]

Yet, they put "Greek homosexuality" in the subtitle.

[1]: "For the Greeks, the concept did not meaningfully exist at all; the social identities we today understand in the West as a gay man or a bisexual woman, for example, simply weren’t something that people recognized."
