becuase some editors surf Wikipedia deliberately deleting articles they consider unfavorable to Israel, falsely using WP policies such as "original research" or "non-notability" (meaning, since we don't want people to hear about it, it's "non-notable");
because there are too many fanatics who censor articles they deem too critical of Israel or Zionism;
because editors who lack basic writing skills make inappropriate deletions or changes;
because editors with a political agenda add weasel words or delete sentences to support their POV (I am reminded of a fellow called Shuki who repeatedly vandalized my article on Rabbi Menachem Froman;
because fighting with all the abovementioned editors is a total waste of my precious time;
because it's sad and frustrating that attempts to improve poorly-written, poorly-sourced, biased, and inaccurate articles in Wikipedia tend to deteriorate into protracted battles that waste everybody's time;
and because this place lacks civility and too many editors enjoy destroying other editors' serious work or forcing their own opinions down people's throats.
As a member of the New York Bar and the Israeli Bar, I have written legal briefs and academic papers on many subjects, both in English and Hebrew. I have practiced law in Israel and in the US for many years. My interests are diverse, and include journalism, law, civil rights, public relations, conflict resolution, music, aviation, and the Israeli-Palestinian conflict. I will return one day to writing in Wikipedia, after some of the fundamental flaws will have been addressed.
