Thank you for the question.

The Order of the Eastern Star is a Masonic mistake in my opinion.  For some reason they adopted the inverted pentagram as their symbol, and as a result of them doing so, practically every conspiracy nut and anti-Masonic religious preacher type uses it as evidence “proving” Freemasonry is “Evil”. 

They are right in once sense, to understand that symbolically the inverted pentagram is (99% of the time) an extremely negative or evil symbol. (see the Goat of Mendes)

The fact that the Order of the Eastern Star does not realize this doesn’t prove they are Satanic, however it does prove they are lacking basic knowledge of Cabalistic symbolism and thus making other Freemasons look bad.
