Astrology is based on the notion of "fixed stars" which we now know to be false. The stars we see in the sky are just some of the 100 thousand million in our galaxy and our galaxy is just one of 100 billion galaxies. That being the case, the idea that these particular stars should have any special meaning is demonstrably absurd. That being the case, how do you justify indulging peoples' search for meaning by using a false system which drives them away from reality?
