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
I can still remember a time when I would never read any comments at all. It was usually about furious debates, name calling, hate speech etc. You know, pretty much exactly what Twitter is known for.
