A good example of diversity in the right way is the Last of Us. Ellie has always been gay ever since she was created. I have absolutely no problem with her character whatsoever. Why? Because she didn't change halfway. In fact, I would be upset if they made her straight all of a sudden.
To the idiots who think there's something wrong with Ellie being gay, shame on you. There's nothing wrong with her. To the idiots who still do not understand what my rant is about, I hope you read this.
