As a moderator elsewhere in cyberspace, I can tell you that "you're angry" is the most popular troll tactic out there. The implication is that anger is
1. always a paroxysm of emotion that clouds the target's mind and impairs judgment
2. always a manifestation of malignant hatred and bias
3. always comes from a negative attitude which the troll, praise be, does not have.
The troll tactic is actually a variant on the logical fallacy of ad hominem. I think everyone here has figured out that it's what a troll does because he's just out to score points for his "team," not really learn how other people think about things, or consider their evidence.
