Astrology is wrong. Ok, that needs no qualification at all. Any number of sources can handily debunk the theory itself. But it's not just wrong. I'm making the point that astrology is, essentially, racism.
From the Astronomical Society of the Pacific's Astrology Defense Kit:
6. Shouldn't we condemn astrology as a form of bigotry?
In a civilized society we deplore all systems that judge individuals by sex, skin color, religion, national origin, or other accidents of birth. Yet astrologers boast that they can evaluate people based on another accident of birth - the positions of celestial objects. Isn't refusing to date a Leo or hire a Virgo as bad as refusing to date a Catholic or hire a black person?
There was a birthday today at my office. Cake, flowers, singing - a joyous occasion to be sure. The boss - the frigging top brass - brought up the fact that it is May, and therefore the birthday celebratee is, whatever, a Gemini or something, thus she has this and that quality and is good at X and bad at Y. My eyes had glazed over red at this point and there was too much steam coming out of my ears to pick up any specifics.
We've played this game before: let's imagine that, instead of finding out her birthday, the boss had just learned that this employee was born to Jewish parents and reacted thusly.
Oh, you're a Jew? That's weird, you aren't particularly funny. You must be great with numbers though, huh? Everyone keep a hand on your wallets! Hahaha, just kidding. Seriously though, have you had a nose job? I can hardly tell you're Jewish!Everyone present would be absolutely agape at that kind of bigoted inappropriateness. Yet when it's in regards to the birthday rather than sex, race, or religion, a good laugh is shared by all.
