Some posters are still talking about teachers 'teaching this subject' as though classes about sexuality, gender, homosexuality, transgender etc are being arranged in primary schools. No they aren't. the No Outsider books are for lower schools in any event as part of the curriculum and holistic work in schools in no bullying, acceptance of others and so on
Most primary school teachers are already very good at all of that. I don't suppose anyone objects to Winnie the Pooh, there's Eyore, with his low permanent low mood and his friends looking out for him. that could be construed as a dreadful thing, the idea of introducing depression as a mental health issue to 3 year olds.
