Of course they are! What a ridiculous statement.
I work in a Primary School and all the kids were learning about it last week. Today we all observed the silence and even the badly behaved kids were quiet throughout.
I had two two-minutes silences today...one with my class at 11am...and then at 11-05 when the next lesson started and my year 7s (11/12 year olds) told me they hadn't had one at 11. They then started asking questions about it and the war in general...my lesson on William the Conqueror building his castles will have to wait, as I abandoned it there and then. Good class, I was impressed with them.
Oh, and we do teach the Holocaust, and Churchill (whatever the papers may have you believe). In fact, even if it was removed from the curriculum, I'd still teach it.
I have been on school trips to Auschwitz and Paschendale, both were very moving and the students very well behaved. In fact, the English speaking guide told me that every year all the guides have a meeting and one of the things they discuss is which students were best behaved. The British students are voted the best year on year on year, they behave the most appropriately, ask the most informed and interesting questions, and generally conduct themselves in the best way. Try finding that in the Daily Mail next time they write about the youth of today.
