&gt; <i>And this is how the troll generates strife. For what he indicates is known to be false or harmful or ignorant; but he does not say that thing, but rather something close.</i><p>Haha, that is naive, or perhaps incomplete. Actually the &quot;worst&quot; trolls simply tell some uncomfortable truth (which isn&#x27;t false or ignorant, and he who respects truth wouldn&#x27;t dare call it harmful).<p>That is to say, sometimes trolls disrupt communities that are formed around &quot;group think&quot;, consisting of members who get together just to be around others who think the same way and avoid those who disagree with the shared ideas.<p>If you surround yourself with others who confirm your opinions, then anyone who busts in with a dose of reality is a &quot;troll&quot;.<p>There are many forms of disruption, with many motivations, that all get lumped into the &quot;troll&quot; category.
