I simply find that the only reason use any sort of iconography is to authenticate the lineage of your philosophy. You can't do as such by simply negating nor defaming someone else's symbols. Thus, I don't seem much of a point to borrowing one either as it is so much easier to come up with your own.
Personally, my aversion is more that the symbols are all rather generic and cross-pollinated with conflicting ideas. The pagans think the cross is representative of the four elements, the Christians thought it was a symbol of Jesus' suffering, and the Egyptians thought it meant life and fertility although in a slightly different form. Even the alchemy symbol for 'sulfur' or brimstone is merely a patriarchal cross with an infinity symbol appended to it's bottom. Such is the silliness... Satanic symbols with Christian origin -- fancy that!

Anyway, other than attempting to cloister a gaggle of mindless sheep to do your bidding these fabrications have no use! :seesaw:
