Actually,in thelema magick promulgated by crowley,same gender se* is considered to be of the highest and purest source of magic.According to their doctrine,now this is what I read from a practitioner's account,it seems se* makes magic potent.But,when the partners are of same gender,then,it multiplies the power by many times.Hence,they make it a norm for the high practitioners to participate in that.
They also think that a person has both feminine and masculine psyches (all that hermaphrodite and baphomet talk) and that one has to act the opposite gender once in a while especially while having relations with those of the same gender to increase the magick in oneself.And that this takes a lot of energy to actually play the psyche of the opposite gender.Hence,such practitioners are actually reveled.
I think all that crossdressing and acting gay is tied up into this line of thinking.
Which made me think that all the nwo agenda of lgbtqpiak movement is about making individuals who are supposedly magically potent without drawing any suspicion.
And then,using these magically amplified people in whatever rituals they are planning to do.
