Sometimes it is necessary to engage him, because he posts his propaganda on every website that discusses Israel. His one point that he tries to make, over and over, is that he tries to convince us conservatives that Israel has to give up Judea and Samaria; as a corollary he maintains that Prime Minister Netanyahu supports a two-state solution.
He somehow believes that using ALL CAPS makes his lies more compelling, and that eliding with dots and ending with smiley-faces makes him look more reasonable.
True, there is no doubt a line of propaganda being spread. One that is decidedly not Zionist, and at times overtly anti-Judaism.
