Judaism is not the state religion of Israel. It doesn't have one. Anglicanism is not the state religion in the UK because it is not the religion of Scotland or Wales, which, last time I checked, are still in the UK. De facto may be another matter, of course. When discussing Israel it is important not to unconsciously conflate Judaism with Jewish ethnicity. In many regards that is the problem when it comes to these spats over antisemitism, which, to me, means attacks on Jews as an ethnic group BECAUSE THEY ARE JEWS. The right of Jews to be regarded as an ethnic entity, not a religious grouping, is to be respected in my view. Ethnicity within Christianity is a far more diffuse issue.
