Do We Have This One?
I don't think we have a trope for a group of people dedicated to hating a work. If there is, I can't find it.
I got this from the fact that people use Fan Haters
to label people who hate the work. That is not right. That trope is for people who put hate the work and
put down others for liking it.
For example, most of the haters of Ctrl+Alt+Del
and Dominic Deegan
just attack the comics, not the fans.
