"Jews" do not "hate gays". Some Jews -- ultra-Orthodox medievalists -- may hold sectarian beliefs that exclude anyone not of their immediate community.
This includes members of other ultra-Orthodox communities that happen to follow rabbis other than theirs, OR Jews seen as insufficiently observant, AND certainly people whose lifestyle does not conform to their religious principles.
I sympathize with them in opposing a gay parade in Jerusalem. They could hold one every weekend in Tel Aviv and no one would mind. In Jerusalem it seems like flaunting their political power to do so, in a place and among so many people who wish to live separately from them.
But the law allows it, even encourages the expression of their rights. In fact, the government of Israel is using the parade to "sell" the idea of Israel as gay-friendly, where tourists can visit without fear of official prejudice.
The only reason for the police response that the article complains of is the violent and deliberately intimidating behavior of these "holy" men themselves. Were their response non-violent and political, the police would not be needed, and the question would solve itself by agreement among all parties.
In fact, because of the tension with the Palestinian Arabs, I believe the gay community is going to hold the event at a university, rather than in the streets. So we see who is showing the responsible attitude here.
From tonight's Jerusalem Post:
The number of police that will provide security during the Gay Pride event on Friday has been reduced to 3,000, police announced Thursday.
