Yep. I think it's pretty appalling so many people still give astrology so much weight, which proves the inadequacy of our educational system. I mean, the history of science, conceptual physics, etc., are fascinating subjects, require little or no math, and could be taught at the elementary level. There is no reason any student entering middle school should believe in astrology or any of the other pseudo-scientific shams floating around out there!
