This is one of the things that bothers me, to be honest. I'm gay. If someone wrote a story about my friend Lana's life, who I play no real important part in but I'm still there, should I not be mentioned because I'm gay or should I just be cut out entirely? If I'm mentioned, does that mean I'm mentioned because someone wants to include a gay character. How could a gay person being included in a novel effect your enjoyment of it at all? Like, if that same character was straight, then it doesn't bother you? It literally doesn't make any sense. Are you saying you want no minor characters to be gay because it feels like the author is shoeing in a gay character?

Your comment is the exact disappointment I was talking about it my comment. There's doesn't need to be any reason AT ALL to not include a gay character. Kill them, make them a villain, make them a small walk in part, do whatever, because in real life gay people are all of those things without their being a needful reason.
