This is not about "supporting the state of Israel." It is about supporting the actions of successive Israeli regimes, with reference to their behaviour towards Palestinians in particular though not exclusively. Gargantuan efforts have been made by several of us in this forum to make that distinction crystal clear. Your final reference, which includes the remark "beyond what you consider justified" seems to show that you are failing to avoid that conflation and are, therefore, falling into the Keith/Bobad/Teribus trap of seeing any criticism of "Israel" as antisemitic. Let's hope that it's accidental in your case.
