As a daily reader and talk-backer on Ha'aretz, I appreciate both the diverse opinion pieces and the ability to voice my views. Although I lean more right than left I enjoy reading what Gideon Levy, Amira Haas and others have to offer as well as the opportunity to tell them what I think about their extreme views.
It's one of the only "places" where radical Islamist Israel haters, anti-Semites, devoted Zionists and everyone in the middle get the chance to go at it with no bloodshed but with words, and that too is something I value. I often think that perhaps one line I write might open their minds and reading what they write often opens mine. There are far too few forums for such exchanges, and we could all benefit by more writing and talking and less shooting.
