(Warning: explicit language in the video link) I saw this video about video game reviews. Simplistically, it explains that people who like bad things and hate good things, are not useless as reviewers.
The usefulness of their reviewing is the consistency of their opinions. If they consistently like bad things, and consistently hate good things, then they become very useful to look at and do the opposite. See what they say and do, and look for the opposite. If they say it's really bad, then it's probably really good. And vice versa.
I had this experience myself. I went to a website, a subreddit for romhacks. I noticed that the commenters would not even play the games they reviewed, and hated on people's work that was put out for free. They would call things "edgy" that I thought looked cool. So I played a romhack game that they hated, and the game turned out to be one of the best romhacks I've ever played. I experienced this effect for myself, of using consistently contrarian views.
It made me think of these sorts of verses: John 15:18, John 17:14, Matthew 10:22, Luke 21:17, 1 John 4:5, and Luke 6:22.
I thought that the principle of usefulness of consistent contrarian opinions, might apply also to Christianity. If the world consistently hates, rejects, or tries to avoid something or someone, that thing or person is very likely worth searching for. The world actually may be unintentionally doing something useful. Instead of looking around randomly, it seems like focusing, at least sometimes, on what the world hates, rejects, and avoids, could make looking for good things and entities and people more efficient. Maybe this principle doesn't work 100% of the time, but it seems like it would work more often than not.
