goes beyond just a sexual context imo. Beyond physical attraction a gay person has feelings of love and affection for the same sex. A fetish in my opinion is relegated to a sexual activity i.e. feet, furries, cuckold, ect. There are gay people who aren't that interested in sex same for straight people. But they still want the companionship of the same sex...that has very little to do with sex.
I can understand this point of view, but what hat you describe in the latter part of this post sounds like it would apply to a small section of the gay community (I don't have the research or anything, lol)...
"Homosexuality" absolutely fits the definition of a "fetish" to me...
