Homosexual nature is not an acquired behaviour...It is a natural instinct and as far as I know it is due to chromosomal or genetic abnormality.
Is Homosexual Natural Instinct Or Acquired Behavior? What Do Objective Research Findings On Homosexual Behaviour Conclude On This?
All of the research to date currently suggests that homosexuality is an acquired trait but is definitely genetically and or prenatally predisposed. Nothing like an attraction is ever fixed. Where you born with a preference for chocolate to vanilla? I didn't think so, now what makes you think you could be born with such an infinitely more complex preference? P.S. Think of predisposition as the things that ultimately lead to your preference to chocolate, but there is no causal link between the inborn disposition and the homosexual disposition itself.
