Iceman after revealing that he is a mutant; the comics version of the character was then revealed to be gay in 2015. Transgender issues also come up with shapechangers like Mystique, Copycat, and Courier who can change gender at will. It has been said that the comic books and the X-Men animated series delved into the AIDS epidemic with a long-running plot line about the Legacy Virus, a seemingly incurable disease thought at first to attack only mutants (similar to the AIDS virus which at first was spread through the gay community). In the film X-Men: First Class, Hank McCoy is asked by his CIA boss why he never disclosed his mutant identity, and his response was "you didn't ask, I didn't tell". Communism and socialism: Occasionally, undercurrents of the real-life "Red Scare" are present or the events of the Red Scare in history are alluded to. Senator Robert Kelly's proposal of a Mutant Registration Act is similar to the efforts of United States Congress to try to ban communism in the United States. In the 2000 X-Men film, Kelly exclaims, "We must know who these mutants are and what they can do," even brandishing a "list" of known mutants (a reference to Senator Joseph McCarthy's list of Communist Party USA members who were working in the government).

The comics explore religious fundamentalism through the person of William Stryker and his Purifiers, an antimutant group that emerged in the 1982 graphic novel God Loves, Man Kills. The Purifiers believe that mutants are not human beings but children of the devil, and have attempted to exterminate them several times, most recently in the "Childhood's End" storyline. By contrast, religion is also central to the lives of several X-Men, such as Nightcrawler, a devout Catholic, and Dust, a devout Sunni Muslim who wears an Islamic niqāb. Subculture: In some cases, the mutants of the X-Men universe sought to create a subculture of the typical mutant society portrayed. The Morlocks, though mutants like those attending Xavier's school, hide away from society within the tunnels of New York. These Morlock tunnels serve as the backdrop for several X-Men stories, most notably The Mutant Massacre crossover. This band of mutants illustrates another dimension to the comic, that of a group
