What you and others in this thread are struggling with is a fallout of a philosophical rift identified more than 2000 years ago by Aristotle, this is “The Problem of the One and the Many …”

Because the consciousness of men permits each man to weigh the perceptions of his senses and apply individual proofs of reason to the nature of existence – men disagree. Some men appear as strange and alien to other men because the nature of their consciousness is so different.

Yet all are men: The one and the many.

In this particular case the problem manifests as the quest to deal with this elusive demon: “the troll.”

Your position that disagreement is evidence of intent to sow discord -- well, for one this is circular, but that is beside the point: People think what they think, and generally for the reasons stated. No evil intent required.

You have confused effect with cause.

The fact of cause is: People think what they think.

The fact of effect, for you is: “blood pressures rising across the board,” an internal emotional response within individuals. 

Your emotions are inside of you – not external to you. The effect is inside of you … not inside of them. 

So, I assert that the “troll” is not a real problem – the troll is an emotional demon inside of you.
