Toxic positivity. I'm not a fan of "your opinion doesn't count unless you agree with me" and this is just a social media platform saying the same thing. But I'm grateful for the Return YouTube Dislike browser plug-in/add-on so that you can have some point of reference among perspectives outside one's own. If a video has 300 likes, you might think it's a fine video and you'll watch it thinking "wow 300 people endorsed this". If a video has 300 likes and 500 dislikes, though, you at least KNOW "oh that's at least one red flag. I shall invest more effort than usual into being skeptical and mindful, and more effort into thinking critically as well, as I watch this."

If i see a ton of dislikes on a video whose topic is one of the new reich's designated scapegoats, the dislike count may in fact be a factor that INCREASES my favorability toward it, because chuds brigading something means it upsets them.
