1. Well, we are digressing to the Gaza conflict, but calling it a genocide is probably just a form of turning up the volume on social media to generate some engagement. It is hardly similar to real mass murders whose goal was destruction of entire nations, that it requires people using the word to ignore the fact of reality that there was no real attempt at destroying the Palestinian people in Gaza. The argument then consequently turns to some legal reading that reduces the crime of genocide to "death of any amount of civilians", to the point it only serves to reduce the crime of real acts of genocide
3. Yes, it showed impressive operational capacity on the ground during the war. However, trying to attribute the protests solely to Israeli intelligence both gives too much credit to Israel, and uses the same mechanism in point 1 that erases the more uncomfortable parts of reality to keep a predefined political idea coherent.
To highly paraphrase, in order to create a myth you shouldn't be concerned with what you remember but with what you forget
