I think that's an interesting difference between the fanbases. As an X-men fan its possible you wouldn't notice Inhumans stuff previously unless you were in the Complex threads etc. But as an Inhumans fan it has literally been impossible to avoid angry X-men fans, they show up in every single one of our threads for as long as I've been reading. If your an Inhuman fan its impossible to avoid the angry X-fans, even if it may not be that large of a percent of total X-fans.
Pretty much every Inhuman fan in this thread is saying its been going on for years, and lots of X-fans were unaware of this.
