This clearly is someone who doesn't want us digging, so because they choose to bother us I will say this much:
There will eventually be threads like this for many cities.
The masons are the largest secret society. Juat your friensly neighborhood occult secret society. Many will claim they are a "front" or whatever, but this is not true. There is the satanist family and the luciferian family. The masons are the luciferian ones. The initiates don't know what they're getting into, and I suspect the bad stuff doesn't get introduced immediately, but let it be known that the masons are not the good guys.
Anytime they come up, shills pop out of the wood work to claim "they're just a front," but they aren't. Not when you start noticing all the handshakes. Then it becomes obvious that what symbols the cabal all seem to share seem to be masonic.
By the way, the owl as a symbol is relevant not because of its eyes, but because its beak is the silhouette of the mason's compass and square.
