I’ve known for years that Roger Waters was anti-semitic scum. He has that special brand of upper-crust British racism, which would see him doing things like referring to Israel as “Palestine” in interviews. A few of my older Brit relatives were the same way: just absolutely never accepted the fact that t3h j00000z could have their own country, and would make statements like: ‘there were no Jews in Palestine before 1948’.
I think he got that teaching from his mother what I understand tragially Roger Water dad got killed at Battle of Bulge that story I hear that effect him was inspiration of Pink Floyd the Wall album
