It’s always fun* when one side of a political issue is advocating for doing something incredibly stupid and the other side makes a list of predictions of all the bad things that will happen when you do the incredibly stupid thing and the other side just says “nuh uh!!”
Then when all the bad things come, true, there’s no credit for being right and no penalty for being wrong.
E.g.,
“The Iraq war will be a quagmire”
“Brexit is the economic equivalent of punching yourself in the dick”
*not fun
