Worth keeping in mind that Shulgin, the guy who popularised MDMA, strongly believed it should only be used for therapeutic purposes. In his view, MDMA wasn't a party drug. I can't remember the quote in PiHKAL but he had a mini-rant about hippies "ruining" the drug by taking it recreationally. To be fair, he was right that it led to MDMA being criminalised, but I remember thinking his view was incredibly close-minded.

What is or is not a party drug is really down to the individual (and the party...)

In Aldous Huxley's "Island", he uses guided psychedelic journeys as a rite of passage into adulthood (among many other sensible lifestyle adjustments). That would make the world a much better place if done correctly.
