There is of course a large element of hypocrisy here. Look at this line in a comment by Yocheved:
Moreover, as you may notice even the Jewish Socialist refrain now from overtly calling him (Atzmon) a racist or an Anti Semite. I tell you why, they are simply afraid. They know that he can take them to court and win.So Yocheved Atzmon, let me be clear, Gilad Atzmon is a hardcore anti-Jewish racist, that is, an antisemite, and a lying hypocrite to boot. See you in court Yocheved.
Just as an aside here. I got the link to SPSC from the Engage site. Engage says in its post that the Atzmon's proposed talk is "entitled not entirely ambiguously "Zionist Control"." This is one of those half-truths that is at least tantamount to a lie. The talk is sub-titled "The Gatekeepers of the Pro-Palestine Discourse." This looks likely to be an attack on Jewish anti-zionists. In fact it is likely to be a smear against Jewish anti-zionists by accusing them of a form of racism. Funny how Engage didn't mention that but it's not just the use of bogus ID to post comments that gives Engage something in common with Gilad Atzmon.
