History, a pack of lies?

We've had a week back at school, and my own routine has gone rather strange. Hz sleeps v late and then may wake in the early hours or I can manage to pray Fajr before he wakes, then he sleeps again until late morning. So DH , on parental leave has kindly been sorting out the morning school run, and so I manage to get some extra sleep once the morning rush has finished. So I'm living in a different time zone nowadays, strange!

Boys have come back from school reporting mixed messages they are getting from teachers re the current Gaza situation. S's teacher (a self-confessed atheist) informed them that the Jews came to Israel 2000 years ago, so it is their land. Their Islamic studies lecturer advised them not to buy Coca Cola nor shop at Lidl. I am glad my kids do reveal what goes on at school so we can give both sides of the story. In a way it's good to get other people's opinions so that answers to these can be thought through, rather than to be caught unawares. However I can imagine some kids just take every one of their teachers' words as true, and don't discuss it with their parents. S had discussed his teachers comments with his classmates at break time and they had agreed on the unfair bias. Just to add, Lidl has denied supporting Israel. Please double check for yourselves, I rarely shop there anyway.
I can never remember current affairs being discussed when I was at primary school, just in 'history' that the Crusaders went to free the Holy Lands. At least this current massacre has been recorded for posterity and only those with hearts as hard as stone can try and justify it. Here is the Israeli spokesman being put in his place for once .(I remember Channel 4 news was the only mainstream News programme that doesn't have an Israeli bias).
