We all know that the Internet, and especially social media, are inundated with
trolls--pathetic, repugnant,
dark triad-afflicted losers (narcissistic, Machiavellian, psychopathic) whose idea of a good time is ruining them for everyone else.
Many will acknowledge that it is a bad idea to respond to a troll. They are uninterested in anything you have to say, only in distracting you from what you were doing, knocking the conversation off track, making you waste your time and effort dealing with them, and causing whatever harm they can. This may be so much the case that they will say things they don't mean simply to satisfy their desire to disrupt and to hurt--but much of the time, maybe, probably, most of the time they believe them, if not always wholeheartedly.
But how does one tell the difference between trolling and an opinion they simply do not like?
I find that trolls tend to butt into ongoing conversations among other people--usually, people of quite a different sensibility than themselves. (To choose an admittedly non-neutral example, one might find, for example, a few people who might all be considered left-of-center responding to an item to which such persons might be expected to be more attentive than their counterparts on the right when a right-winger suddenly turns up.)
I also find that when they do butt in they do one of three things:
1. Fling insult and abuse. (All they can do is call the participants in the conversation stupid--which often betrays that this is exactly what they are.)
2. Rub their opinions in the faces of people they expect to be repulsed by those opinions, rather than try to actually discuss anything. It is a little harder to be sure of this than, for example, insult. Still, there are giveaways. Such opinions are typically canned, often by someone else (they don't actually do much thinking for themselves, or they'd have better things to do than this), and commonly irrelevant to the conversation into which they have entered. (I recall a thread where people discussed the President's reply to the Thanksgiving Day question "What are you thankful for?"--and only that--and someone felt the need to inject the claim that "Socialism killed 100 million people.") When others react, they commonly display satisfaction, perhaps repeating the action.
In cases I have had the impression that they are like exhibitionists, deriving satisfaction from others' disgusted reactions. In others, they seem to delight in lobbing a grenade into a crowd of bystanders. In still others, it seems they are more purposeful--intent on diverting a discussion, for example. (I recall the comments thread of a news story about the Netherlands' police training eagles to catch drones, and seeing it from the start diverted into an attack on solar energy, with the hundreds of comments that followed caught up in the ensuing flame war. Alas, renewable energy and sane climate policies are very common troll targets.)
3. In the rare case that they are able to actually interact with others regarding the subject, they behave in very unreasonable, bullying fashion. They do not ask for an explanation of another person's opinion, they demand that they defend it, and raise the bar for such defense very high--asking for the equivalent of a doctoral dissertation, complete with footnotes, as the price of their having opened their mouth. Even after the person has given such explanation as they have to offer, the questioner refuse to accept that the other person has said their piece and keeps coming at them, as if intent on making them recant, on converting them to their cause. (I have, unfortunately, found myself having such talks with proponents of atomic energy who want me to "admit" that renewable energy can never be the foundation of our energy base.)
Can normally decent people find themselves acting in ways similar to this? It's not impossible. Annoyance, a foul mood, and they slip into some bad behavior. But I think one can go too far with the "Everyone can be a troll" line, and certainly anyone who has doubts about a particular interlocutor can, on Twitter at least, just look at their account, see the way the suspected troll has chosen to present themselves to the online world, see the things they choose to post and share.
Some I have seen proudly and not at all ironically write the word "Troll" in their bio. And I find it best to take them at their word.
When I run into someone fitting someone fitting the profile described here, I don't mute the conversation, I block them. Permanently.
Yesterday, one of my comments proved to be pure troll-bait, alas, inciting dozens of attacks from people who responded in exactly these ways. I have blocked each and every one, and at the time of this writing, find myself continuing to block them--setting a one-day record, which is, I suppose, why I buckled down and wrote up this post.
I strongly urge everyone else to similarly block those who conduct themselves in such a manner. Trolls, especially as defined here, may have the right to speak, but you have no obligation to listen to them, let alone answer them. They have no right to take your time and attention, let alone inflict harm upon your mental well-being.
Do not let them do it.
