I can't read through all this misinformation to see if anyone has mentioned why she is making a triangle. There is a movement among the Hawaiians to prevent the construction of a 32 meter telescope on Mauna Kea, a mountain on the Big Island. They are using the triangle to represent the mountain as a unity symbol, not as a commitment to the NWO satanists.
Maybe do a little investigation before you start making your paranoid accusations.
