This discussion has reminded me of my concern that parents complained about a brilliant and unusual teacher at my girls' primary school. When my eldest was in year 5, about 3 years ago, they had discussions about LGBTQ and trans issues, and gender and sexism, amongst other things, apparently she thought that 10 year olds were old enough to vote and should have the opportunity to discuss these issues. This was in a quite working class area of mixed ethnicity and religion, the teacher was British Asian, and she also talked to the class about her background and how important books and education had been for her. She left half way through the year. I wrote to the head about how great she was and a very 'neutral' response.
