This is quite the angry rant, but I don't use the words angry or rant in the derisive sense.
The points you make are clear and obvious to nearly no one, and they have to be restated over and over again so that maybe the wind can hear them.
Beneath all of this discussion is something much more psychological, which is why facts really don't help much. It's like trying to talk sense into Trump supporters; it's not possible to do with historical, political, and psychological facts, because the reasoning has to do with feeling — to sate a feeling of some sort.
Studying the history of antisemitism, which I am sure none of the protestors who you mention have ever done or cared to do, we find a very strong inculcation that underlies today's thinking. In simpler words, people are acting and thinking a certain way because of reasons that they are not consciously aware of. And because of this, their words, deeds, and beliefs have created an inner and outer conflict.
It is now and has always been okay for the rest of the world to ignore the plight of Jews in the same way that Americans can continue to ignore the plight of Black citizens and Native Peoples. People are like this; they have an attitude of, "if it's not me then what do I care?" Only the antisemitism problem is worse in that people have been calling for the genocide of Jews for thousands of years. Zionism was born out of this need for emotional and physical security. Nothing more and nothing less.
Excuse any typos; I wrote this in the midst of doing several other things.
