It wouldn't have been suppressed by academia in the past though. Psychologists were distrusted for years by the gay community for their work in conversion therapy, and there were absolute horror stories of people basically being imprisoned and electroshocked 'therapy' to get them to change, including lobotomy and implanting electrodes in the brain. They would have loved the evidence then, and would have published it.If there was data about people going through a “gay phase” it would probably be ruthlessly suppressed by academia. Assuming that it’s true though, does it mean that someone was gay and became straight or that a bisexual was dating members of the same sex and then started dating members of the opposite sex?
Also, there's a large number of people admitting they were wrong about conversion therapy working, including Exodus International and Robert Spitzer.
