The piece on the MP about gendered young adult and children's books made me remember a specific incident in grade school when, for the first time, I realized teachers could be full of crap. I was in Gr 4 or 5, I think, and asked my teacher why all our books and short stories featured boys only as main characters (seriously- the only girl I remember from those English class books was a little sister in 'The Road to Agra'). Her response was that boys only liked reading about boys, whereas girls liked reading about both boys and girls, so this way was best for everyone. I clearly remember thinking that that answer was stupid and unfair in a way I had never come across- I knew I was right and she was wrong, even if I couldn't articulate why.
Thankfully, I had other teachers that felt differently. In my next year, my new teacher couldn't change the curriculum, but in the afternoons she read to us books like "The True Confessions of Charlotte Doyle" and "Island of the Blue Dolphins", which had everyone, girl and boy, on the edge of their seats.
Do you have specific memories like that, where you first knew concretely that the system was broken, that the establishment was wrong, or just that someone in authority was clearly wrong? Tell me when you first raged against the machine :)
