I don't think so. A troll is someone who is intending to cause dissention, not simply debate and share information. We should be open to receiving new information. Trolls are trying to cause trouble

Not at all. I value people who disagree with me respectfully, even if we ultimately agree to disagree.

I see trolls as those who are dedicated to creating dissension, divisiveness, conflict, and drama, possibly even trying to motivate anarchy for whatever nefarious reasons they might have come up with; or for which they have been paid to post.

But there have always been such people, either as paid disinformation minions like those caught in the Nixon scandal, or in personal relationships as we see with emotional vampires.

It means different things in different contexts. For instance int eh gay world a 'troll" refers to an ugly old (and usually fat) man who tries to pick up on younger guys.

No, it's that little fucker l have to pay to cross the bridge.
