YouTube comment sections are weirdly positive always. It could be a video of some horrible crime and the comments will be about how great the channel is and encouraging the channel to keep making more videos. When j visit actual fan pages anywhere else online there are always a mix of opinions. But youtube is constantly full of obsequious people
small channels especially for niche stuff you have people who actively sought out the material and are happy to offer thanks or constructive comments. large “mainstream” channels comment sections are a mixed bag of rants, irrelevant nonsense, sometimes a comment on the subject matter, abusing other commenters and people who can’t help wedge their politics and toxicity into any bloody conversation
