There are many that automatically call anyone that dare to disagree with their views as a troll.
There are indeed. I'm not one of them. As one of my favorite message forum rules states, "We welcome lively discussion!" I
like a good, solid, in-depth discussion! It's how we learn new things, including the errors of our own shortcomings.
Logical discourse is usually centered around a disparity of opinion. But if it's limited to that, then it's not logical discourse. It's merely disagreement. Logical discourse requires at the very least an acknowledgement of another's opinion before refutation. Wall-sized memes do not acknowledge the other's position. They lack reflective listening. While they're certainly a form of refutation, they're certainly not logical discourse, in that such memes fail ti dissect the other's position into its constituent elements before rebuilding them in a more logical form.
During true logical discourse, each exchange -- volley, if you will -- requires the responder to reexamine his or her own beliefs, often refining one's position throughout the exercise.
Posting memes, however, is the antithesis of logical discourse. In fact, it fails all three first steps. It fails to acknowledge the other person's position. It fails decomposition. And there is absolutely no reconstruction. There's not even the three-year-old's "You're wrong" before claiming to be right. It's rather pathetic, actually, a totally one-sided failure to acknowledge anything but one's narcissistic "I'm never wrong" position.
What's been happening here, however, includes not only such failure, but the next step, as well, immature poking, button-pushing, needling, and similar efforts whose only purpose is to upset others.
That's trolling. And it's not as rare as you might thing. Some 5.56% of all Internet users regularly engage in trolling.
The also have a propensity of using insulting names often limited by the forum rules about name calling, a tactic used when they can't defend their position with facts.
Exactly.
Disagreeing with someone does not meet the dictionary definition you posted above...
You're right, it doesn't. What has occurred here goes way beyond mere disagreement.
...unless they consider differing views as disruptive, and clearly some right wing snowflakes here do feel that way.
I think you missed the wholly disruptive and non-constructive nature of their posts i.e. the "trolling" part, those "dark traits," specifically, the high levels of "psychopathy, narcissism, and most specifically, sadism." These are the reasons why I called them trolls and why they're on ignore.
