Why are there people who hate other ways of Fortnite?

I often gamble on Fortnite and get really often with how people are insulted last on a Youtube broadcast by name

You can never do it

There a boy called and said he was playing Fortnite and when I read the live chat I saw news like:

Go bury yourself!

Go die!

Or

Fortnite child all on him

Why?

Everyone has his own game that he likes or dislikes But Dan talks to / about the person disgusts me. There are also only people who like to play the game. I'm still insulted as a stupid and nothing-learning Fortnite child.

WHY?
WHAT DO YOU HAVE AGAINST PEOPLE WHO LIKE TO PLAY?

I mean, of course you can say that you don't like this game but then end a friendship or want someone to die is just stupid! I also don't like GTA or battlefield, for example, and I'm offending other people now because they are playing it? NO!

Go outside and bolt with the others - by far!
