There was a bit to mock there - of course, we did it ourselves - but some of the mockery kinda missed the point of what propaganda is. Sure, Carlson comes across as a sheltered oligarch's heir who never set foot on a supermarket before. But the part where Carlson spends a lot of money and pretends that groceries are exceptionally cheap in Russia works. It plays into the psyche of the far right in the US, the idealization of Russia as a conservative meccah, and into newly accelerated inflation fears in the country.
All in all, the context is that western media is extremely salty that Tucker went beyond the pale and platformed Putin. So, once again, these are just words thrown at the wind. You have to be an american liberal conservative and card carrying Democrat voter to be outraged in that way. Everybody else is either taking the interview seriously or making fun of the culture clash of Putin explaining 600 year old history to an american talk show host.
Another thing are all the jokes about how catty Putin was towards Tucker. People broadly speaking made fun of Putin fucking with Tucker, calling him a failed CIA operative and such. They did it because it was funny. But libs online felt the need to talk about this like they were scoring victory points in the upcoming election. A mirror to that is how people like Alexander Mercouris liked to talk Tucker up as a respectable journalist conducting a respectable interview, not a huckster being used and abused by an prominent statesman.
