The Transgender Industrial Complex flourishes in the void of cosmological understanding created by dogmatists who reject the doctrine of reincarnation.
Theta neural oscillations seem to induce past life memories. This seems to occur no matter the reason. There are several reasons this happens to people including sensory deprivation, hypnosis, and naturally occurring theta dominant states that occur in children between ages 2-7. Evidence shows that all 3 groups experience altered states of consciousness that have been determined to be past life memories.
The University of Virginia's Medical School's Division of Perceptual Studies has decades upon decades of research into this subject with thousands of confirmed case studies. According to their case studies, approximately 10% involve a change of gender from the previous life to the current life.
Perhaps of equal import on this subject is the fact that, regardless of whether or not there was a gender switch between lives, case study subjects generally exhibited preferences, affinities, vices, phobias, sense of social status, etc. of the previous life.
This is likely heavily correlated to the LGBT population. Certainly there are members of the LGBT population who are there because of one of a myriad of other reasons, sure, but I would bet that many are gender switch reincarnation cases who experienced past life memories as children of life as the other gender and, due to the void created in cosmological understanding by certain dogmatic religious traditions, these kids do not receive the cosmological framing that they need to integrate the experiences of past life memories that they had as young children.
