"Refusal will result in a Racial Discrimination note being attached to your child's educational record..."

What is the single most depressing aspect of this letter? Is it the idea of labelling eight-year-olds racists? Is it the moronic conflation of religion and ethnicity? Is it the ugly grammar (“As such our expectations are that all children in years 4 to 6 attend school on Wednesday…”)? Is it the bullying tone? Is it the unconscionable choice of font? Is it that someone can write that way and yet hold a position of authority in a school?
