The eu did surveys in ghaza that showed that 60% support hamas and its islamo supremacist goals. They really want to kill those jews badly, the only thing they dislike about hamas is that it is not winning.
Support for Hamas has generally been in the mid-30s, but that is also skewed by the fact that Hamas also provides things like health care and food for poor. But why do you think it matters? Israeli support for the genocide in Gaza is more than double that. Should we destroy 80% of civilian Israeli infrastructure, starve the population and stop baby formula from getting into the country, have the worlds most moral snipers shoot Israeli children, and then set up a faux humanitarian organisation that shoots at hungry people?
