Sorry to go all Godwin's law, but astrology can and has been used as a tool of oppression. Nazi Germany had a state-sponsored astrologer, Karl Ernst Krafft, appointed by Deputy Führer Rudolf Hess and Chief Propagandist Joseph Goebbels. Krafft was employed to write astrological propaganda that justified anti-semitism on the basis of celestial events. He was also tasked with using astrological observations to predict threats to the Führer Adolf Hitler and offer military advice.

Ultimately, it's not the stars and Moon that do the oppression, just whoever is in charge of divining their meaning, which is also pretty much how religious oppression works.

Given the chance, Saturn would remove women's right to vote.

A belief system that makes claims which are demonstrably untrue is susceptible to being used to oppress people (or elevate them unnecessarily).

Astrology is bunk. Yes I am fun at parties.

Astrology has specifically oppressed swaths of women in the Indian subcontinent. Search for "manglik" for starters.

I’ve seen plenty of instances of people being treated unfairly and unjustly due to religious astrology beliefs. Especially women (of Indian descent, also Chinese but my experience is more limited there).

If the moon doesn't oppress women, then why is the menstrual cycle the same length as the lunar cycle?

Checkmate, atheists astrologists!

Additionally, the stars and moon actually exist.

I dunno, I've heard many women and gays complaining that Mercury is retrograding them, or something. /s

there's one star that is oppressing albino women and gays though

Only people can oppress people.

A lot of folk religions exalt third genders and women into religious positions. It is the major world religions who put down women and third genders are the problem.

Hey, if the stars and planets affect people's behaviour... Just saying.

One could argue that they lift people up, since there's a slight canceling of the effect of Earth's gravity when they're over head. Conversely, the opposite is true when they're on the other side of the planet.
