Your explanation is fair. I am not going to get on Sarah threads until she announces she is running for President. They are a waste of time and resources. However, I wish her the best in her endeavors.
Here’s another aspect of trolls that probably most would agree with (and also that there are different kinds of trolls) - an honest member just avoids the threads that don’t interest him. A troll will glom all over threads that supposedly don’t interest him/her, make cyncial, snide, snarky and belittling comments again and again. If not a bona fide troll, at least a maladjusted person who just likes making a stink and aggravating people.
Sometimes an honest non-troll might make comments of disagreement of course, but the disagreement will be on-topic, not throwing crap into the punchbowl!
Just a couple of thoughts about the matter in general...
