scratchme1010 - Most think a troll is the Under the Bridge type. Or a monster that just bashes things. And maybe there are those types.
But in fishing, trolling is putting a lure or bait at the end of a long line and cruising around the lake (or ocean) looking for a fish to bite. Catch fish, throw in boat, eat or toss away. It isn't about educating the fish (unless you catch and release..) or having a meaningful conversation with it.
To me, people who troll, are having a joke at someone else's expense. Or spewing out things without the least intent of backing it up. Or maybe they want to make a speech that drags others down, then leave. Ring doorbells and run. Say things they don't mean in order to get a "rise".
Sure if you have an unpopular opinion, you're going to get some heavy feedback. But those that are sincere will take the heat and defend. Right or wrong. I wouldn't consider them trolls even if their viewpoint defends the JW religion. Unless they just turn into the bashing troll lol.
