You can refer to god and you are really just talking about nature. If you are going to say the universe is god, then everything is god, everything is religion. But when we explore traditional religion we are talking about humanistic gods people pray to, that they think can intervene in their lives, who run sort of a heaven-and-hell operation for the afterworld.
I've known gay people - men and women - since I was a young person. To me it's just naturalistic and realistic to portray gay characters in a humanistic light. As a young man, I knew enough gay people as people not to fear them. On the other side of the coin, I like to irritate conservatives and homophobes.
I think that the scienti?c way of looking at the world, and the humanistic way of looking at the world are complementary. There are important differences which should be preserved, and in trying to do away with those differences we would lose something the same way as if we tried to make all religions one religion or all races one race. There is a cultural diversity that's very valuable, and it's valuable to have different ways of looking at the world.
