[undecisive]

Colonialist: To my mind, it was the 's' on the phrase "primitive peoples". In other words, it is implying that people in our "civilized" society suffer from this, but those more primitive peoples outside of our society may be exempt - simply because they do uncivilized things that our civilized ladies wouldn't dream of.

Classist: Because of course, that's bunkum. Because even in 1960's "civilized" american society, maybe the upper class lady would keep herself "in confinement" but that doesn't mean that the majority of women would or could.

So no, I wouldn't say it's anti-classist.

(Note: I had presumed that George Blonsky was a doctor - but no, apparently he was a "mining engineer". I suspect he would have been reasonably well educated, but maybe not if he thought spinning pregnant women around to expel their babies was a good idea. So I don't know - maybe the classism was accidental. But it's definitely there.)
