AIBU to expect that a TV programme on a Saturday afternoon on a childrens channel shouldn't have an episode without a warning at the beginning debating the rights and wrongs of gay fostering / adoption.
Watching last w/e with DD who is 8 I felt that it was completely the wrong vehicle for this issue. DD is aware that there are same sex couples and that it's fine. The whole episode concerned one of the characters being fostered by a gay couple. One of the other characters objected strongly and was vilified to the point of being bullied by everyone else in the programme. They were not told off for their behaviour, because their view was correct.
When I wasa kid this would have been an adult drama or discussion programme not on the bloody BBC childrens channel at 3pm.
