So it's OK to accuse a country of rape and genocide when it isn't true?
That's a bad comparison. It was never America's intention to kill all Vietnamese because of their race.
The First Amendment protects the rights of people to speak on issues of public concern. I see you complaining a ton about people accusing Israel of genocide. People accused President Biden and probably every President in my lifetime of genocide. The felon was accused with COVID. Bushes in Iraq. Clinton in Serbia etc. Would you have jailed those people? Does the accusation make them anti American?
Actually, many people said and continue to say that Mai Lai and Abu Gharaib (among other instances) occurred in large part because our mostly white military didn't value their lives. Now, I am not saying that is accurate or inaccurate, but I do think discussion about it is protected by the 1A.
In the case of Israel, their "leaders" have said things like "the Arabs are voting in droves" and that hospitals should be segregated based on religion. Another had a picture of a terrorist who massacred Palestinians praying in a mosque hanging on his wall. To say that any questioning of these people's intent is antisemitic is an absurdity.
Do I think it's a genocide? No. Do I think the Israeli gov places minimal value on the lives of Palestinians and is engaging the way it is, overruling generals and bombing aid workers because its far right leaders that praise segregation and terrorists face certain defeat at the ballot box when the war ends? 110%. That is backed up by Netanyahu funding Hamas to perpetuate his own political survival and prevent his own criminal trial from taking place.
Since Netanyahu also bombs aid workers and has killed his own citizens, I think he'd kill basically anyone to not lose power and avoid jail. Much like the Hamas terrorists murdered Thai farm workers and Arabs living in Israel. It's brutality and murder by people whose goals are strictly self perpetuation at any cost. Lives don't matter, race and religion aside. It's terrorism, not genocide.
Of course, most Israelis and most Jews globally, and most people generally don't support this behavior. So the idea that any questioning of it is antisemitic defies logic.
You are essentially just saying any criticism of Israel's conduct is antisemtitic, which would basically make most Israelis antisemitic. Not logical.
