There's no mention of the minister in the article you linked?

Ben-Gvir is a right-wing populist dipshit who's unfortunately part of the government, but nothing will ever come of it. If anything, I blame the club for not telling the foreign players in advance what the banner is about. "Bring them home now" is as uncontroversial as a statement in this time can be, I doubt anybody would have objected to endorsing it.
