'I don't understand why people got so upset about Dorian's homosexuality. I mean, it's canon but this doesn't stop anyone from downloading mods or writing fanfiction or just plain headcanon-ing their female Inquisitor as his lover. Hell, other fandoms do it all the time with their fay characters.' If it sounds wrong to do it to a gay character, please don't do it to a straight character.
I understand what you’re saying but Dorian was a really, really bad example to use being that his sexuality is a major part of his history and personality, and affects him in a lot of aspects of his life, such as his relationships.
I think there is a difference from doing it with a gay and a straight character, though I’m not sure if this is a good fandom to do it in for the reason that there is a severe lacking of LGBT+ representation. There’s absolutely no lacking of straight representation.
A lot of the people who bend characters’ sexuality are either:
LGBT+ people who want characters who are like them
One is an issue separate from this, but you’ll see that in bending a gay character’s sexuality, the first group is completely omitted because there are TONS of characters who are like them. Which leaves the fetishists who probably want to romance Dorian so they can have the sassy GBF boyfriend. He’s used as an item by a vast majority of the people I’ve seen who mod him straight, where a character headcanoned to be homo/pan/bi/ace is made that way to give the person something to grab onto and feel validated.
