People are stupid. I lump people who call other users trolls, when they obviously are not, in the same category with the users who post, "vs threads are bad" or "search bar!", when ten users before them already pointed that out.
In doing that you're purposely attaching your own point of view onto that persons opinion. The problem with this concept, that someone is "obviously not" a troll, is that you don't know that for sure - and someone could see that person in a different way.
For example, I could claim this very post was trolling, by your definition, because you're "throwing insults" at people, (in this case you claim "people are stupid") whilst at the same time appearing to imply you are not. Regardless, I disagree entirely with your perception of a troll; if that was the case there'd be no trolls on most sites because people aren't foolish enough to post something as obvious as your examples. (That I shall take at face value, as they are, after all, examples)
A clever troll will disguise their true intentions, and as a result you wouldn't know they hadn't seen that TV show they claims sucks, because they'd find opinions that support the view you don't like through the internet.
In short, your argument is highly flawed, mainly because you attach the stigma of troll onto either a great many people, or none at all - displaying you don't appear to fully understand the typically know what typically defines a troll.
