It is a made up “fact” by someone on twitter: that JD Vance wrote about fucking a couch in his book, Hillbilly Elegy. Some people retweeted it without checking the sources, and it just continued on from there.

No sure about that. While he was alive he could do things/get stuff done to him which would get reported in the news. Getting poisoned by Novichok, getting arrested in a Russian airport, disappearing and reappearing in an Arctic gulag – all of these things show up in the news cycle, giving us constant reminders of the how bad it is in Russia. Now that he’s a martyr, I guess his name will disappear from headlines until maybe the anniversary of his death.
