Well, Politico is not exactly a non-partisan source, but pretending they aren't lying, there are ~35K people employed by the FBI, and 10s of thousands more "formers". So it is entirely plausible that Politico found some agents who loved Comey, while "trof"'s friend is acquainted with agents and formers who hated him. It's not like 10s of thousands of people are lockstep in their thinking.
