Yesterday they claimed he physically assaulted an israeli journalist, today they've changed it to "made threats" and didn't physically touch them at all.
So in summary Joost Klein beheaded 40 babies and mass raped women.
To be fair we don't know exactly what he did. From what I've read it sounds like he somehow harassed an employee in the production crew, which honestly should be reason for exclusion. Assuming that is what happened, it doesn't seem unjust and I don't think the other participants should try to justify such behaviour.
According to the dutch news orgs, he made a “threatening gesture” towards a (female) camera operator, after he asked not to be filmed, repeatedly (there were not supposed to be cameras at that point, so the request was not unjustified). There was no physical contact.
