That is the official party line - this year.
It is propaganda of course, and false. Other agendas are in play.
Homosexuality is a spectrum disorder primarily caused by environmental and hormonal stresses on the mother during weeks 8-24 of pregnancy. It weakens the development of normal sexual polarization to opposite-sex attraction, and resistance to same-sex attraction. Or it reverses the polarities to some degree.
Homosexuals can also be "made" by early and intense sexual exploitation of children, and adolescents. It depends on how strong their natural sexual polarities were before exploitation. It also depends on how skilled the exploiters may be and whether they catch their subjects at critical times where they are vulnerable to change. Results are always uncertain for any particular target. Most people cannot be turned after puberty sets in. There are always a few exceptions though.
Well said.
