As usual, Tgo, you are incredibly wrong.
It was an allegory for all minority experiences at various points in time, but the LGBTQ influence is well-documented. Brian Singer has been incredibly clear about using the movies as allegories on the gay experience and used it to recruit Ian McKellen for the role of Magneto, for example:
Meanwhile, the Legacy Virus was an explicit allegory for the HIV/AIDS epidemic:The actor who's starred as Magneto in the X-Men films also said he signed on for the films after director Bryan Singer explained to him that the mutant superheroes serve as an allegory for the gay community.
Also LOL at your idea of acceptance: "I don't mind gay people as long as they don't talk about it". How progressive.Comic books also saw their share of HIV-inspired storylines. In 1993, Marvel’s X-Men faced a threat like nothing they’d seen before: the Legacy Virus, a communicable infection that harmed only mutants. The primary symptoms were nearly identical to advanced AIDS: skin lesions, fever, physical wasting – but before the virus claimed its victim, it would cause their mutant powers to flare wildly out of control. In Uncanny X-Men #390, Colossus deliberately infected himself with the cure, an act that saved every mutant on Earth but cost him his life.
