'll put this as best as I can. I'm an odd man out in the FF community. I don't like canon characters in the first place, but I feel like if you are gonna do them you do them as close to canon as possible. I can't stand outside random shipping.
So when it comes to this I feel it's basically the number one F U to the character. Most often it's done to fulfill some sort of ship and not because it actually adds to the character or makes a good character.
To a degree, I get what's going on here. I for one grew up on the original PJO books. Never had anything about Nico's sexuality so when I wrote him he was straight and that character was MY character that's what he meant to and was to me. The second series not only felt like a betrayal to the original series (seriously so many retcons and plot holes) that whether it was intended or not in the first series I saw the Nico story as a retcon.
Same time I'm also a catholic and honestly I don't support the whole LGBT idea (It's not like I'm out there stopping anyone. I can disagree. If you're gonna do something in your home I can't stop you, but I also have the right to keep it out of my life.) So if I find a character I like and they turn out to be in that category yes I have ignored it or changed it. Partially because if I portray it as wrong I'd get even more flack.
There was a time when I genuinely sat down and thought about whether or not I supported these ideas and in the end, I don't see them as positive or useful in any way, so they are either negative or not important. I'm certainly not going to support them then in my work. At best I see it as a mental disability where the body has reactions to the same gender instead of the opposite. It's not a crippling disorder, but it just sounds like a disorder to me. (You can be happy while having a disorder. Plenty of people here are on the autism spectrum or adhd or plenty of other challenges, but they aren't things to parade around like they are distinctly good. At best they are not bad.)
TL:DR I don't support the LGBT, so I make everyone straight, but typically avoid canon characters so I've only done it twice. Deal with it. My right to disagree is just as strong as yours. I'm not stopping you from doing anything, so you can't stop me.
. As someone who is both on the autistic spectrum and gay: those two are not even remotely the same. One of these has caused major issues in my life, makes me depend on other people for help, causes disruptions in my relationsips with other people, among other things that I'm not going into here.. ]
Being gay has done none of those things. I don't want to say it enhances my life, either, because it's just something that I am. It's an inherent trait that I can't change, just as much as I can't change that my eyes are blue or that I'm really short.
I know its inherent. But you decide whether or not to engage. Same way there are ways to lessen symptoms of other conditions. I was on medication for years to gelp with my adhd and aspergers. Now ive developed the self control and communication skills that I dont need the medicine. I still get distracted and find it hard to talk when shouted at, but im high functioning now.
Im not saying a gay person is bad I just see it as a more negative condition. In the same way youd treat a disorder i feel homosexuality should be treated. The discrimination where people were stoned or institutionalized is cruel, but it doesn't mean i think the condition is good.
If there was a cure id see it as a universal requirement.
