The guy is a kook (and I dont mean student of Rav Kook). Read his comments after the article as well. I remember I had a fight with him as well (don't even remember what it was but perhaps something to do with Rav kahane ZTL or the loony "kabbalah" that he preaches maybe both.
In his comments and the article itself he goes after Rav Kahane ZTL HYD as well as Rav Eliyahu. Gladd people called him out on it.
