My mom is deaf and I grew up using that sign. But honestly the creator of the sign was Hellen Keller and besides the TV shows and shit about her there is some evidence she was a occultist. I know the idea of a deaf blind satanist is kind of funny. But it seems to have some legs actually. Story is she created the sign as a kind of joke. To fool deaf to making a basically satanic sign everytime they said I love you to someone.
And Galludet the American premier college for the Deaf was started by an occultist and his daughter wrote a book on the esoteric magickal properties of Salt. So maybe nothing we have been taught is fucking the truth. The lies are endless and the mockery of the normies is extensive.
