My God, I do. I hear these views expressed quite openly by lifelong supporters of Palestine.
One elderly white gentlemen absolutely roared at me that ' The Israelies have absolutely NOTHING to complain about, about what happened to them on October the 7th' . Another, again a white left wing man, supporter of Palestine, is basically an atrocity denier, believing its all been made up by the BBC, that people may have been killed but no rape or brutality took place, and that I only care because I think I have to because of the Holocaust. Another white left wing woman, another atrocity denier, who does air quotes every time she says ' the Jews.'
These are people who consider themselves good, compassionate people, openly expressing these views in casual social situations.
Its absolutely shocking the open levels of dehumanisation of Jewish people. Absolutely shocking. I now understand how things like the Holocaust do happen and its through the views expressed by these 'good, caring' people who cannot in anyway see their own racism.
