Based on my limited experience, because I have kind of discussed it with my Jewish friends, the people most strongly for this kind of violence tend to self-select into actually moving to Israel, hence the people in Israel, tend to support the genocide. Outside, you tend to have a mix of elites who back Israel, and more middle/working class Jews who are horrified, but don't have the social capital or NGOs to make their voices heard. It's a bit of a broad brush generalization, but as a general trend.

It always comes back to socio-economic class.
