Anon, when have "they" ever created anything?
You say "their symbols", but this implies that a symbol can be created and/or owned. Let's break down the symbolism of… Say… An equilateral triangle. Can "they" claim to have created the symbol of an equilateral triangle when the meaning of such a symbol arises from the truth of its foundations?
Anyone can wear a symbol, but a symbol only holds power when it is consistent with the truth its structure is built upon. People who simply try to flash or wear a symbol are doing the "magical equivalent" of autistic screeching.
Think of symbols as a sort of math. You can string together all the numbers you want into something that appears meaningful, but 1+1 will always = 2.
