Oh yeah, symbology is going to change over time, but this isn't an abandoned culture, it's still actively used by catholicism and the current pope.And ancient greeks thought the pentagram was simply and expression of mathematical perfection. I'm not saying douchebags who think they're flipping the bird at the heavens by turning a cross upside down aren't douchebags, but symbols mean what groups of people agree commonly they mean, regardless of who intends what.
