The guy you're talking about is Chris Miyares who said of Fetterman in 2021 that had done "more good than on bad act".
But more importantly you're overlooking that that is not a policy position. It's a character flaw.
I'm not a big fan of the superhero/Rambo attitude for exactly this reason. It's dangerous and it's delusional and far more likely to get people hurt then help anyone.
But that doesn't change his policies.
Ok?
