the Temple Mount means nothing to secular Israelis
Then what are they doing living in 'Eretz HaQodesh (the Holy Land)?
That was the wrong place to put a secular Jewish state!
I am a Masorti (Conservative) Jew and by Israeli law I am defined as chiloni even though I am observant.
Now if you are trying to claim that perhaps 14% of Jews in Israel don't care about the Temple Mount then I will wholeheartedly argee with you. If you are trying to claim that 70% don't care then you are just plain wrong. Any Israeli Prime Minister who tries to cede the Old City in Jerusalem will suffer the same fate as Ehud Barak: their coalition will collapse, their government will fall, and they will be cast out into the political wilderness forever.
