Maybe I am wrong. I've observed usually the most aggressive to be kind of "knight of the status quo." They are opportunists seeking status and notoriety, whether consciously or not. They do this by being opportunists and attacking those who offered controversial opinions which garnered feelings of negativity. The knights latch onto that negativity as their opportunity for an assault. And you'll find they have put little genuine interest into the actual issue at hand, they're more interested in being a sort of "knight of the groupthink." So I think it is not really surprising to find users with their real names associated with conformity and status-seeking.
