JP and JC
JP and JC refer to Jordan Peterson and Jesus Christ, whose videos occupy an outsized portion of the YouTube search results on a variety of important subjects.
The worst topics in this regard include belief systems, meaning of life, tradition, temptation, and morality. You really have to dig to find anything on these subjects from a secular or progressive perspective.
While both do have good advice from time to time, videos from these sources will not be provided on this wiki. We won't do that to your algorithm, lest you end up in the manosphere.
