Why all the hate?

You ever go on Facebook and see a cute video? Or on a group someone ask a question? You want my advice? Never read the comments.
I do not know why but it turns into a berating session. The cute video comments are all about how horrible what is happening in the video is, to how dumb the people are who are saying it is horrible.
The questions in groups are often met with snide remarks or insincere replies.
And for some reason people always have to pull politics into it.
I simply do not understand why people have to be this way.
When I disagree with a post or don't like a video or think a person has asked a really stupid question, know what I do? I keep scrolling. There is enough genuine crap in this world that we do not need to add to it with stupid mean comments.
Not really anything I can do about it I guess, except to keep ignoring the hateful stuff I see on others post. Oh and be greatful that the hate hasn't found its way to my own posts, videos and questions.
