When I post online, I'm pretty much always in my roleplay mode where I pretend to be my wyvern character. That's when I say things like "I'm a wyvern" or I go
But when I want to talk about my character or my identity, I'm in a more distanced mode where I'm just ...me. A human who's sitting behind the keyboard, who created a wyvern character to handle his identity and feelings.
There were times when I was talking about being a human, and then I got a reply saying "but you are a dragon!"
That would've been fine if I had been in my roleplay mode, but I wasn't. I was talking about my identity. And that's when I don't want to hear these things at all, because they only hurt.
I know these people meant no harm, so I don't hold it against them. They couldn't know.
