Glad you asked. As the title of this thread indicates, this discussion is about the Israel Lobby in the United States.The discussion was about whether or not the US considers Israel to be a valuable ally. I'm not sure where weaponizing anti-Semitism plays into that discussion.
Any criticism of this lobby is met with charges of antisemitism, as you have demonstrated yourself. That's where the weaponization comes in.
It is possible to criticize the actions of a foreign country, or those who advocate on its behalf, without hating them.
We can criticize the governments of Russia, or China, or those who act on their behalf, without being accused of hating Russian Americans or Chinese Americans.
So why not Israel?
