I suppose you have seen lots of good videos that have thousands of views and a bunch of likes, but they also have two or three dislikes, if the video is popular about 100 or more...

I want to know what thought process do the people who dislike videos that you can not find reasons to dislike, like a wildlife documentary, a video about awareness of cancer, idk, every harmless and inocuous video in yt has a bunch of dislikes. Who does this? Why?
What do you think /bant/ers?
If you do this thing of massive disliking every video you see, why do you do it?
