Here's where he starts bringing it up. Also, keep in mind that the title of the video is referring to his first guest, the guy talking about the history of the region is his second guest.
OK-- so the idea is that the description of Israel as an 'apartheid state', as well as the equation of Zionism with racism and fascism, are rooted in old Soviet propaganda?
That's quite a weak argument, to be honest. Zionism is in essence a form of nationalism, and it would be simplistic to say nationalism is necessarily racist. But it's also true that the
formulation of nationalism that numerous politicians are pursuing is explicitly drawn along ethnic/racial/religious lines, and aims to exclude others. The so-called 'Nation-State Bill' explicitly ties the state to a single specific ethnic group above all others. It's difficult to conclude that that's not racist in nature.
The government also operates in a manner that is clearly prejudicial against one particular minority group-- affords them less legal and practical protection; subjects them to routine abusive practices by state military and police actors; and pursues illegal thefts and violence against people of a specific minority within the territory it controls. The government also allocates resources prejudicially, depending on whether the recipient is from that minority or not. These are all aspects that we identify as characteristic of an apartheid state when we look at South Africa.
