Your method was already recognized long before by John Strawson, who noted how the "use of selective quotations from right wing Zionists is not balanced by quotations from left wing Zionists." More broadly, Strawson notes the simplistic criticism of Zionism follows the path noted by Edward Said in his criticism of Orientalists: "First you essentialise the category you are dealing with and then you select who will speak for it...The result is a construction which does violence to complex realities. One-dimensional Zionism is as misleading as one-dimensional Islam" (Strawson). Enough of this one-dimensional thought on Talkback already.
