I think you underestimate the entertainment value of intentionally posting inflammatory things. It's fun to play devil's advocate. That doesn't mean you believe it.
This is a ridiculous, not to mention untenable, position. I take it you never read Socrates? He saw great value in poking and prodding -- being the proverbial gadfly.
That behavior is acceptable in an academic setting, but nobody blithely posting contrarian or inflammatory content on a fansite or Facebook is doing it because they're hoping to inspire Socratic discourse.
You have two choices: (1) execute Socrates, or (2) accept Socrates as part of the Miltonian "marketplace of ideas" and leave him be. I'd like to think we've started to see that (2) is a better choice than (1). Dismissing Socrates as "aggressive" (and implicitly "dangerous") is, from what I can tell, not the right move.
