It really is a shocker, isn't it? Such a laugh it seemd at the time. I actually bought the 12"!
I was thinking about how The Kinks' Lola, from almost 20 years earlier, used a similar imaginary encounter for comic and dramatic effect, but with a degree more sensitivity.
Little, if any, progress in the intervening years. And as you say, we simply absorbed all that crap as our natural cultural milieu, in pop music, sitcoms, everything.
Frightening. But also reassuring in the way things have changed so much in the years since. And again frightening in the urge shared by many to backslide all the way to even earlier.
An unfortunately apposite reference point for your story.
By the way, I've now finished that 'song for my funeral' piece I mentioned, and will submit it to the pub now, once I've imported and formatted it.
Then maybe think about a Funky Cold Medina/Lola article.
