"You argued your case but you just can't convince the unconvincable "
Excuse me, but that is not true.
(1) "Unconvincable" means dogmatic, and I for one would believe in astrology in a heartbeat if there were any evidence whatsoever that it works.
(2) She didn't "argue her case" at all, except for some mumblings about how it works for her or some such. Was she able to say how it is supposed to work? No. Was she able to point to any proof that astrology works? No. Was she able to answer my post on errors / shortcomings of astrology (see below) which means it cannot work as advertised? No.
So how can you possibly say that she "argued her case"? From where I sit, it looks very much like she doesn't even have a case

Carl Sagan's "The Demon-Haunted World" debunks astrology in a pretty irretrievable manner. From memory:
Astrology only looks at celestial bodies known to Ptolemy, and completely disregards those discovered through modern astronomy in the last 1800 years or so.
It ignores the asteroid belt and satellites within our solar system, not to mention myriad others outside it.
It disregards atmospheric refraction, which means objects are not where you think they are, with the distortion increasing closer to the horizon. Even Ptolemy knew about this so really, there is no excuse.
Astrology also ignores precession of the equinoxes, which Ptolemy also wrote about.
So even if celestial bodies affect our character and future events (and there is no evidence that they do), astrology goes about charting these so-called influences in a completely wrong way.
