You seem to justify the offensive epithet by the fact that he "has been a strong supporter of Israel, and fundraiser for it, in the past 6 months." What he has been fundraising for is the UJA Federations Israel Emergency Fund. The UJA Federations Israel Emergency Fund donates money toward equipping hospitals and first responders, aiding those in poverty and providing critically needed trauma counseling. https://www.ujafedny.org/israel-emergency-fund That is not funding or enabling genocide.
If someone repeats Hamas propaganda and attacks Dems with it, then yes, they are a tool of Putin. It only serves to depress the Dem vote, which will help elect Trump, who will let Putin "do whatever the Hell he wants."
That 33,000 deaths figure you cited came from Hamas, and Hamas includes Hamas fighters and noncombatants in that total, and includes deaths from any cause.
Former U.S. Defense Secretary Mark Esper was interviewed on CNN by Anderson Cooper a couple nights ago. He said Israel has taken out 16 of the 20 Hamas battalions in Gaza. The remaining 4 battalions are in Rafah. When asked about civilian casualties in Gaza, Esper said 1/3 of the total casualties reported are Hamas fighters. He added that the number of civilian casualties in Gaza is equal to or lower than the civilian casualties caused by the U.S. and other western nations during urban warfare.
This is especially remarkable given that Gaza is densely populated and Hamas is embedded among the civilian population and using them as human shields.
Esper added that the fact that Israel is engaging in ground fighting, rather than exclusively bombing Gaza, has lowered the rate of civilian deaths while placing Israeli troops at greater risk.
Israel is defending itself, like we would do (and did), yet when Israel does it it's called genocide. The Nazis "Final Solution" killing 6 million Jews was a genocide. The Hutus killing of 800,000 Tutsis in Rwanda was a genocide. Gaza is not a genocide. Holding Israel to a different standard than other countries is antisemitic.
