Here's how he describes Derek Jardine, the keffiyeh-clad bloke doing the honours instead of the familiar Sandra Watfa, who hasn't appeared at these Inminds demos for some time:
"Like most of Inminds activists and the majority of anti-Israel protestors, Jardine is a conspiracy theorist obsessed with Jews. He shares posts from those like Atzmon, is friends with some rabid far-right racists and I have presented evidence before of his 9/11 and Mossad conspiracy posts."And Collier provides the screenshots to back up his assertion.
Amusingly, as this video by BDSer Alex Seymour aka Seymour Alexander shows, towards its end, from 11:01 or thereabouts, a hero strides forth, to the annoyance of the Israel-haters.
