I cannot imagine living a life in a way that I am victimized by the lack of support for my favorite, 2 dimensional, high hatted, slaver superhuman hero group. The Inhuman hate has nothing to do with made up or imagined biases and everything to do with their lack of character. If there is proof of anti diversity hate targeted at the Inhumans...by people who favor mutants, I am both confused and uninterested in seeing it.
The Inhumans and Xmen are competing for the same niche, and the Xmen, by virtue of not being slavers with a crap 2d royal family who soak all the attention, do it better. If you find yourself having to constantly defend a maligned superhero group, maybe find a better superhero group?
This has nothing to do with X twitter, and everything to do with first exposure from the Kirby era of Inhuman development. I don't particularly care for the X books either.
