"However, are you not suspicious of people who single out Israel for attack, always and only criticising Israel while ignoring much worse rights abusers all around Israel?"

No I am not. If we are discussing Israeli policy, it is perfectly valid to criticise it without having to go round the world comparing Israel with everyone else. There is no double standard. In other contexts we criticise US foreign policy, Assad, the Brexit liars, Thatcher's neofascism, Blair's lying warmongering, Putin's hubristic manipulations, and, well, a lot more. Insisting that we always criticise someone else as well every time we criticise Israeli policy IS the double standard. You are guilty of that, and, in so doing, you are being antisemitic.
