There are two kinds of people: those who understand it’s juvenile humor and are just memeing on it for funsies, and those who don’t understand that and are never going to be high information voters and JD Vance fucks couches must just be the message that gets them to vote.
My optimism in humanity leads me to believe there are very few of the latter. What I’m certain of is the joke does no harm and is a silly little meme. President Trump was a silly little meme in 2015 but then Hillary ran the worst campaign in living memory (Kamala saved Biden from that dubious distinction), and here we are. So I’m okay with it, but obviously it has no place in serious conversation except to inject some laughs.
