I mean Jewish eradication in ww2 was an extremely big deal, and on the largest targetted scale.
But yes, it has sort of replaced all the other stuff. Intellectually disabled people were some of the first targets, and Roma. Queer people were targetted and the allies left them in the camps which is digusting.
I think the important thing is that it is not who was targetted by whom but that the process by which we demote one kind of person relative to another is the actual evil. From that only horrors can follow. That is what has allowed all genocides and what allows Israel's current war. If it was wrong to view Jews as some subhuman class of people, a problem to be managed, then it is wrong to view Palestinians that way.
That many Israeli do not feel this way (the war is extremely popular) is disgusting.
