I think virtually all of The Capricorns don't believe in Astrology Nonsense. But, I'll put in a plug just so we who are born during "The Shank of Winter," can at least be represented. We are normally way too busy controlling and manipulating events and individuals from behind The Throne, to ever mess with this sort of stuff! Me, I'm just a Maverick.
Peace and Love, Joanie
P.S. What I see so far, is about like that claim of CD Left-Handedness. You are going to have to look a lot further to find a "commonality." Astrological Signs aren't The Answer.
