Welcome Charlie,
You may or may not have noticed that this message board is sincerely dedicate to learning, discussing and understanding the teachings of Evolutionary Astrology, not to questioning it's validity. As a learning style, you may have the need to compare and contrast the teachings of EA to other systems that you understand and/or believe in, but the EA message board is generally not the place for that. You can refer back to the post on how to use this message board and read through other threads to more fully understand the intention of the message board.

Warmest regards,
JJ
