I think what parent means is that /astrology/, per se, is mostly consumed by women, whereas Jung's work, which can be viewed as similarly unscientific, is quite widely read by males, when compared with astrology texts.
At least: I don’t see this choir of “but it’s antiscientific!!!” cries when Freud is discussed, but still there’s no evidence whatsoever for the tripartition of self which is at the very base of Freud’a theories.
The super-ego is no more scientific than synchronicities!
