The difference between writing about a character and writing about an actor is that Aemond Targaryen will never read a post about himself, he won't be upset if he finds out someone has recorded him without his permission, he won't be uncomfortable when someone writes a smutty story featuring him or writes comments saying that someone'd love to lick his belly or bite his nipples. He won't be furious when someone writes a non-con or dub-con scene involving him or that someone has made him a pervert because he doesn't exist.
But Ewan Mitchell does exist. He is an actor and what he deserves is respect and support. He's never asked for anything more and wants nothing more despite what many people here may think dreaming of what they will do to him when they meet him. He's a wonderful man with angelic patience and a warm, open approach, he doesn't need anyone's protection and he's doing fine, but it's sad to see some people turn their unhealthy obsession with him into something that is dangerous.
