While this is a good point, and true for a lot of people, I feel there’s also a large number of people who would specifically be interested in a game because of having this theme. As far as my own preferences go, I feel there’s value in having a mix of games where I’d get to escape from discrimination and ones that would really engage with the topic. I guess it falls a bit under the sliding scale of escapism… it’s good to have stuff on both ends and all the way across the middle…
I suppose having it be focused on a fictional minority depends on whether it’s a contrived metaphor for a specific real-world group, or whether it’s more of a worldbuilding thing 
I do get what you’re saying, and I often feel this too, but I’d worry about seeing a story falter for this reason 
especially since I think it’d be a theme that’d be really interesting to write about…
This is a bit off topic, but I think it could lead to interesting discussion and viewpoints… if anyone thinks it’d be worth discussing further I could start a topic on it… or someone else could, since I’ll be going to bed soon
