Yes, when two people disagree, one side commonly thinks the other side's argument is nonsense. But, as you admit you don't know the truth of the story, it is impossible to tell whose side is right. Maybe the editors do just think it is garbage journalism. Or maybe the editors are just protecting "their guy".
It isn't impossible to tell who is right or we would never know anything. Maybe Ted Cruz's dad assassinated JFK or maybe he didn't. Who knows, both sides say the other side is nonsense.
