WHY THE JUSTIN BIEBER AND ONE DIRECTION FIGHT?!?

[Iamnotonfire]

~~ACTUALLY READ THIS BEFORE ANSWERING WITH SOME ANGRY RANT.~~
Now. I'm starting this by saying that both artists like eachother. One Direction likes Justin Bieber, Justin Bieber likes One Direction. Deal with it.
I'm so SICK of some directioner trashing the Justin Bieber fandom, or some belieber bashing the One Direction fandom.
SICK.
OF.
IT.
If you like one of the artists and hate the other, fine, good for you, have your own taste in music! But why do you feel that it's necessary to go saying awful things about the other??? Calling someone else fat won't make you skinny, calling someone ugly won't make you pretty, and calling someone untalented will not benefit you in any way.
SO WHY DO YOU LOOK UP STUFF YOU HATE SO YOU CAN WRITE MEAN THINGS.
WHY.
I don't trash either fandom! I love both! Yeah, I have a favorite between the two, but I'm not going to say which one I favor because undoubtedly someone will send me hate for it!
So just answer my question.
WHY.
