The problem with so-called reparative therapy, based on the expert opinion of all of the major psychology/psychiatry groups, the experiences of its victims (who are still living), and all reputable studies is:
It does not work,
it inflicts terrible damage on vulnerable people, and
it wastes time money and resources that could be spent helping people.
Even the conservative church I grew up in tried it for decades, and for all their efforts of the experts in their social services division, and in their church run universities, they found the only measurable result was that they could consistently take gay and lesbian youth who did not have a porn habit, and addict them to masturbating to straight porn. They could also create a lot of divorces and broken homes if they succeeded in encouraging the gay and lesbian youth to marry the wrong sex.
As for seminaries, the ministry, military academies, liberal colleges, any of the places that some suggest 'create' or 'convert' straight or cisgender young people into LGBT people, no one has ever been able to show that anyone can be recruited or converted to a new sexual orientation or a new gender identity.
Some professions and some environments do seem to attract more closeted and open LGBT people, perhaps because certain personalities and sensitivities do seem to be more common among LGBT people than in the general population, and recent research is beginning to show what some of those positive differences tend to be in various groups, explaining why evolution has clearly not evolved us out of the human, or other animal, populations even with millions of years to work with.
There is a proven correlation, however, between supportive and "out" peers, and coming out of the closet one self. The more tolerant an environment, and the more role models of successfully happily living as ones true self exist, the more likely a suffering child is to escape from shame and despair and find acceptance themselves, whether that child experiences a difference in sexual orientation or in gender identity and expression.
