It's not really a factoid, so it's an interpretation you believe to be true. Which is just a truly held opinion.

On top of that, unpopular opinions are not trolls.

Even if you were a troll; good-natured trolling has value. This is why Haterjuiced (a Leftist troll) was here for so long. He never violated the rules, and never took it too far. He pushed the boundaries of conversation away from the forum-wide opinion, thus keeping it from being an echo-chamber.
