Forbidden to pray

In a JPost article entitled, "Intolerance on the Temple Mount" David Kirshenbaum writes about his visit to the Temple Mount.
"But now that I was standing in that holiest of places, which generations of Jews for 2,000 years could only dream of visiting, I was forbidden to pray. Simply moving my lips in whispered prayer could be grounds for removal. Why? Because I am a Jew. And only a Muslim can pray on the holiest site in Judaism. A Jew may not. "
He further writes, "Israel has scrupulously upheld Muslim worship at the Aksa Mosque, which was built just off the supposed site of the Temples, even when the site has been used to stone Jewish worshipers at the Western Wall and sermons are delivered calling for the demise of Israel and the US. "
In contrast, "Israel has, for the past 43 years, failed to challenge the Muslim ban on Jewish worship on the Temple Mount. On our visit, the number of Jews allowed up at one time was severely limited, we were checked for any religious items, which cannot be brought onto the Temple Mount by a Jew, and we were warned by the police not to even whisper a prayer. "

Why should Jews be banned from praying at their holiest site? Where is the tolerance?
