The language used, and the memories regarding his relationship with Gellert Grindelwald did suggest that Dumbledore was in love with Grindelwald to a lot of readers even before the statement by Rowling. That said, a lot of out queer folk have had the experience where someone was surprised that we identify as queer, as if there were visible indications of queerness functioning as neon signs.
What I think is part of the issue in the case of Dumbledore is ageism, frankly.
Like I said, it's been awhile since I read the books or watched the movies, especially the latter half of the series.
I don't know if ageism was on my mind, at the time. I just remembered being annoyed of being told outside of the books/movies. (I was pretty young, too, and was struggling with figuring out my sexuality and gender stuff.)
That's an awfully declarative statement. That rather depends on the character and the text.
You can have all sorts of sexual orientations and be single. To argue the opposite is potentially falling into the chasm of gay = sex. You don't stop being queer because you're not in a relationship.
I can't speak for CL Polk's intended message or meaning, but I can understand being a bit frustrated if all of the straight characters got all of the interesting romance stuff, and the only token gay had a very celibate relationship or not have a relationship, at all.
I don't think it's unreasonable to be a tiny bit irked by that kind of trend in the past. (Luckily, that's changing, and society's changing as well.
)
But again, I don't know if that is what CL Polk is referring to.
I apologize for my forwardness and to be argumentative (and it could be that I'm in one of my down moods, at the moment), but I tend to have a strongly dim/pessimistic view of the limited amount of LGBTQA characters that I do see in my limited viewings and readings.
It's getting to the point where I'm always expecting most LGBTQA characters to die, angst, or be celibate or single, or just be the token secondary character. Again, it is the limited media I'm exposed to, but the little I've seen doesn't really provide much reassurance.
I'm glad things are definitely changing, though.
I'm just frustrated, being in a conservative environment. I feel very stifled and stuck, and I sometimes have trouble finding good, positive, or non-stereotypical representations of LGBTQA characters in my favorite kinds of fluffy, non-violent, or not-depressing shows/books/movies/etc. (I'm going through one of my periods of internal anxiety and depression, at the moment. The whole being Christian while being LGBT thing is also stressing me out, as well.)
