I really want to go to the big demo in London on Saturday. What is happening in Gaza is so terrible and I feel so powerless. But I have two small kids (6 and 3) and while I have taken them on a march before and they loved it I am concerned that on this one there may well be images on placards and so on of terribly wounded /dead children, as well as a lot of anger in the air. I really don't want them to be frightened (though of course I know children in Gaza are suffering a million times worse) Should I protect them from these possibilities or do you think it would be valuable for them to be there?
