I don't see Norma as a victim of trauma as much of an archetype of lost youth and glamour. Maybe that's from where I sit in my life. But the emotions that are stirred up by the music are ones of regret and the refusal to retreat and die. That's pretty universal. I think it's legitimate to read Norma as a victim of trauma but the tendency of the current era to wedge every story into a trauma narrative is a bit like an earlier generation trying to fit stories into some kind of Freudian mold.
When the film was made, none of these issues (misogyny, ageism, mental health) were popular concepts.
I've always seen the film as a critique of Hollywood itself, hence Joe being included it its satirical edge. He finds love but gives it up for material comfort. Or how the studio not only wasn't interested in producing Salome, but wanted to rent her car. It's a satire of the heartlessness of the whole town. And Norma is an unstable little bird who gets crushed in its gears (whatever weird metaphor that is).

Funny you should say that: the only thing I vividly remember about Scandalous was the absurdity of a 50-ish Carolee Carmello playing Aimee Semple McPherson as a teenager.
