Sully was a TROLL, not a journalist or even a legitimate columnist.
By which I mean HE DIDN'T BELIEVE THE BS HE WAS SPOUTING - he was just (constantly) trying to score more clicks by pissing people off - it didn't even matter to him if he contradicted himself within the same column.
It works, btw - up to a point - eventually as he was figured out, all he was doing was dragging down the reputation of the whole paper.
