I must respectfully disagree. This is Judaism's holiest site. Even non-observant Jews revere the Temple Mount and the Western Wall.
By the way, I strongly suggest a visit to the Western Wall. I personally watched people, non-observant Jews and non-Jews alike, who were completely overwhelmed just standing in front of the Wall.
There is a very strange feeling that envelopes one there. It is impossible to explain, but it is, nontheless, absolutely tangible.
I'm not at all intending to pick a fight. All I'm arguing for is tolerance so that people who believe strongly about the importance of a rock can enjoy it in peace.
