It’s hard to square this statement against the 13-to-25,000 estimated (Assoc Press vs Al Jazeera) dead women and children in the last 6 months though. Just objectively speaking, that is a shocking number of civilian deaths even at the low end.
Did you have similar outrage when the Russian air force was dropping 1000lb dumb bombs on similarly densely populated cities in Syria from 2015-2017? I guarantee you a lot more civilians died needlessly in places like aleppo and palmyra than Israel has ever 'slaughtered'.
Remember that Hamas operates most government functions within Gaza, so anyone seen doing organizing work to help Palestinians survive could be categorized as a "Hamas operative" by the IDF.
