That is good advice.
I am from Israel, and so many American Jews identify being Jewish with the Shoa, Arab persecution, whatever. Even (to a less extent) Haredi with their black cornered caps -— a mark of past persecution.
Being Jewish is a people and a religion.
Teaching that being Jewish means you are going to be a victim is a bad thing, and makes children, especially American Jewish children, not want to be Jewish.
Be strong. Be a soldier. Be Jewish (of any variety you please, in my opinion — there are 12 tribes are room for disagreement).
King David was not a victim.
Take it to them, by all means necesary.
