Left-Hand Path
The historian Dave Evans studied self-professed followers of the Left-Hand Path in the early 21st century, making several observations about their practices:
They often reject societal convention and the status quo, which some suggest is in a search for spiritual freedom. As a part of this, LHP followers embrace magical techniques that would traditionally be viewed as taboo, for instance using sex magic or embracing Satanic imagery.[1]:197 As Mogg Morgan wrote, the "breaking of taboos makes magic more potent and can lead to reintegration and liberation, [for example] the eating of meat in a vegetarian community can have the same liberating effect as anal intercourse in a sexually inhibited straight society."[5]
They often question religious or moral dogma, instead adhering to forms of personal anarchism.[1]:198 They often embrace sexuality and incorporate it into magical ritual.[1]:205
