hatedom

A Fandom that is dedicated to hating a work, idea, community or author, instead of loving it.

Of course, to have some form of credibility, it's best to have actually read/watched/played/listened/joined/followed to some of the hated work, but some people usually hate without having any knowledge or something parroted to them by another hater.

If you hate the fandom of a loved work, you part of a Hatedom.
If you hate the fans of a fandom, that makes you a Fan Hater.

A Fan Hater does not have to be part of a Hatedom.
Anti-Fans of a work are likely to view its fandom as a Fan Dumb.
Fans of a work are likely to view its Hatedom as a Hate Dumb.

Haterdom 

To be continually in the act of hating other people's ideas and lifestyles, based solely on your poor outlook on life, and not on actual, concrete facts.

Katie's constant haterdom makes it easy to see why no one likes her.
