Exactly! Nobody I went to school with had never heard or had any concept of homosexuality. In my early teens I was shocked to learn of sex between man and woman. "My mother and father would never do that," I remember shouting out.
I learned about homosexuality later through men coming on to me. I encountered men who I would now describe as 'camp' but had no idea what they got up to. Something, instinct, sixth sense or Our Lord maybe, preserved me in my innocence from the advances I was subjected to. None of these advances were from priests or teachers I might add.
In school those picked on were as you say the fat boys, the smelly, the unathletic, the unusual, etc. Now this did not include all the fat, the smelly, etc, which means that personality also played a part.
British Catholic bishops, apart from a few, are card-carrying members of Corbyn's Labour Party, especially Cardinals Nichols and Murphy-O' Connor, the latter a member of the Sankt Gallen 'mafia'.
