Mazin Qumsiyeh has posted a rather nonresponsive response to my extensive documentation of his record of adopting and promoting anti-Semitic ideas. No explanation, for example, of why his website hosts an anti-Semitic article on “Jewish Power” written by a Holocaust denier. He calls my claim of anti-Semitism “defamatory” but fails to point out anything I wrote that was false. Qumsiyeh adds that my “‘personal attack’ consisted of copying a couple of articles from Zionist extremists who have long been discredited and you have never bothered to contact me for the facts.” In fact, the evidence in my original post consisted primarily of links to two articles Qumsiyeh himself wrote, a blog post reprinting an email he wrote, and an article hosted on his own website. Straight from the horse’s mouth, as it were.
