It’s always been a reality, just one that society chose to ignore due to a huge set of reasons (religion, western imperialism, colonialism just being a few of them). SE, while not being a beacon of social awareness or progressiveness, has had LGBTQ+ content in their games (not nearly enough, though. It’s very upsetting). While never verbally stated as such, it’s no secret that Vanille and Fang from XIII are in love. NieR and NieR: Automata are LGBTQ+ friendly games. SE publishes Life Is Strange and both sides of the company really love the series. After a very large push from fans worldwide, XIV started allowing same sex marriage in the game.
SE needs to move the needle forward, though. They used to be trendsetters in the industry.
On Disney, they aren’t really the issue. Disney has their limits, especially if they are concerned about hurting their bottom line, but they make progressive moves when they feel the time is right. Disney would also never hinder SE if they decided to have LGBTQ+ characters in KH. At the end of the day, it is really what Nomura wants...and he isn’t the most...in-tune guy? Not socially aware?
