This one has been bugging me for years.
X-Men (and Spider-Man) are the reason as to why I got into the Marvel Universe. For a while they were my favorite team and to date they still occupy a unique position in the Marvel U so I have to ask... why do some people want the X-Men to be placed in a separate universe from the rest of the Marvel U?
I get that ever since Chris Claremont's defining run the X-Men have indeed mostly existed in a vacuum with many heroes not facing the same level of hate as mutants and things like Genoshia being ignored by the Marvell U at large... buuuuut I always thought it was just lazy writing. To me the idea of the X-Men being in a vacuum was more of other writers and even the X-Men writers not taking into account the idea of the larger universe outside of their own books.
Though I dislike Avengers vs. X-Men, it at least called to attention some of the hypocrisy going on in-universe and again while I don't like Uncanny Avengers as executed, I loved the idea of actually trying to bridge the 2 halves of the Marvel U and still do. IMO actually trying to remember and recognize that the Avengers and X-Men parts of this world are not mutually exclusive and face the consequences (say Captain America being attacked by Anti-Mutant extremists, or Cyclops leading a special strike force against Kang given the X-Men's propensity for time travel adventures) is a better answer then just copping out and making the X-Men completely stand alone.
Integration (no pun intended) of mutants into other books would encourage thought, social commentary of racism vs. legitimate threats and misaimed racism (IE, Spider-Man being mistaken as a mutant and embracing it) just seems like it opens far more interesting options and stories. Granted this stuff should still be predominantly handled in the X-Men books themselves but don't have other heroes just ignore the issues constantly presented. Plus why deny the crossover fodder?
Those are just my thoughts. What are your thoughts? Why do you think the X-Men SHOULD or SHOULDN'T be thrown out of the Marvel Universe?
(PS-Any argument involving movie rights will be ignored on my part. I'm dealing with comics here not movies. Just FYI)
