First of all I’m fed up with people being castigated for airing opinions that are contrary to the demands of the politically correct. Secondly, Ann Widdecombe is a practising Roman Catholic and like a lot of religious people clearly believes that homosexuality is a curable 'condition'. We have friends who are devout Baptists and, like Ann, they do not regard homosexuality as ‘natural’. Terrified that their gay son will go to hell, they pray constantly that some day a ‘cure’ will be found. Who knows? Maybe it will. I very much doubt we know all there is to know.
(I don't know if anyone else (possibly Mibs, Nailit and Theland?) will remember an ABer from years ago - a Muslim turned Christian - who, together with a couple of friends, hired an exorcist to try to cure his gay friend. Taking it a bit far we thought - but then he was odd in more ways than one so not entirely unexpected).
