Quelles sont les causes de l’homosexualité?

Pour l’instant, aucune explication n’existe pour l’homosexualité. Comme nous en avons déjà fait mention, principalement depuis le début du 20e siècle, un grand nombre de spécialistes s’intéressent à la question. À ce jour, aucune conclusion définitive permettant d’expliquer l’homosexualité n’en est ressortie.

La plupart des théories explorant cette thématique ont tendance à être peu fiables à cause d’importants biais méthodologiques. Aussi, peu de ces théories explorent ou expliquent la bisexualité.

Ne faut-il pas voir les choses autrement?

Nous pouvons nous poser la question : n’est-il pas un peu étrange de se demander ce qui peut causer l’homosexualité, mais pas ce qui peut causer l’hétérosexualité? Pratiquement aucune recherche scientifique ne s’intéresse réellement aux causes de l’hétérosexualité. Pourquoi devrait-il en être autrement avec l’homosexualité?
