This is definitely a taboo topic.
The idea that Jesus was gay has been promulgated by the UFMCC for about a decade. An Australian man received a government grant to write a thesis to prove Jesus was gay.
The whole basis for this idiotic theory is based on a total lack of understanding and knowledge of Semitic cultures plus modern psychology. It also flies in the face of other legends that state Jesus married Mary of Magdalene and escaped to Europe after His faked death on the cross. There is a family in France (I believe) that actually believes they are descendents of Jesus and Mary. There was a book written about this family about 20 or 25 years ago but I don’t remember the name of the book although I did read it.
