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 only subscribe and comment on channels I REALLY like. I only have 13 and one of those is just so I don’t forget to watch a follow up video tomorrow. I think it’s because it’s video content. Every video has click bait titles to appease the algorithm and I don’t think anyone is sure if they’re sarcastic or serious unless they watch the video, so they’re not sure if they should be mad about it and just don’t bother commenting. Text based content is easier to skim for the authors actual point of view. If their position is already known, I think you’ll find plenty of shit talk based on the title alone from people that were just driving by.
