Agreed the X-men are bassically outcast who participate on their fictional world in politics but who also have super hero adventures like other characters.
I also agree marvel needs to introduce new characters from those minorities, do a second "All New all different X-men" that era gave us Storm, Colosus, Nightcrawler, Banshee, Shiro, etc where there are mutants from all around the world, the complicated thing is giving them the place to breath and give their own unique perspective accoding to their understanding of the world but a skilled writer could do it imo. As a Magneto fan part of what attracted me to the character was the way marvel didn´t hide his experiences, still they could do a little more to write him as a jewish person in the day to day basis.
I like Emma, Hank, Scott, Jean, Logan, Charles, Magneto et all but we also know their stories and the X-universe is big enough to tell new stories and made them matter in the bigger picture.
