I don't know if it's most people, do you think so? From my own life, there has been almost only nice people in real life. Social media though is very different and people act like it's not a person on the other side of this screen.

A threat? How would that be? Not to mention that essentially nobody is like me, so others being different is the absolute norm, the opposite of hard to imagine.

I say that could be sad because not laughing is like nit eating tasty stuff. Not feeling nice things. A whole dimension of positive stuff simply missing. But specifically about the topic of feeling and lack of laughing is, more or less, sadness.

Let alone that you are actively against laughing of others, and that absolutely is sad to me.
