There is a place for legitimate criticism of Israeli policy - but I draw the line at calling for the death of Israelis. It isn't criticism; it's just hate speech.
The problem that I'm trying to pull up here is that this is not an isolated incident of a single person posting hate speech. There is a large group of people who celebrated the events of October 7th, and are passing that hatred on to their children through education.
I didn't forget the hate speech on the other side. But they don't include it in their official government sponsored school curriculum.
