I’m assuming every Talmud Torah in Gateshead isn’t mentioning homosexuality in any way, shape, or form.
Of course they don’t. However, a lot of the failing is due to the reactions of the children selected during the inspection, and it is likely that in most frum schools – at least in the high schools – there are children who are exposed to the concept of same sex marriage on some level. Depending on the child’s initiative, the answers can vary in standards and can often reach the pass level even without being taught. Viznitz, however, would be blatantly clear that the children do not know of or support homosexual marriage.
