Dimi Reider didn’t actually explain why it’s illegitimate to demand that Israel be recognized as a Jewish state (state of the Jews, for the matter, as I explained in the previous post). He stated that Israel’s self-definition is a somewhat debated issue and then claimed it’s wrong of Netanyahu to demand recognition for Israel as a Jewish state, because there is some debate around it.

The point is that the debate is not whether or not Israel should be an Jewish-ethnic country (although you might object to the idea, the vast majority of the Israeli populace doesn’t), but as for the how Jewish, as in religious vs. secular-ethnic-centric that country will be. And this is where Dimi leaves off and simply bashes Israel for things not related to Netanyahu’s demand. No matter how you look at it, it’s just bashing when the criticism is done using a faulty excuse.

“Just another opportunity to bash Israel again” – again, easy way to not differentiate between the different arguments (“bashings”), nuances..
would you care to pay attention to what people actually say, or are you so afraid that you shut your eyes after 2 sentences and murmur ‘anti semitic islamist multiculturist self hater yada yada yada’.. ?

As Dimi Reider says in the article, the subject of how to define the state of Israel is of some debate within Israel itself. Judaism being both a religion and an ethnic group is the root of the problem – there’s no difference in English when using the word Jewish, but there is in Hebrew. Of course Israeli-Arab leaders wants Israel to be defined as a zero-ethnicity bi-national state which will essentially mean the end for the national Jewish homeland idea as defined by the UN at the time (a still-binding document if I remember correctly).
Defining Israel as a Judaist state or Jewish (as in a people) state is a very delicate subject, with a small majority for the former.

This discussion has nothing to do with the (correct) analysis you give here, but might confuse those who are unfamiliar with the term.
