I was just reading the trivia section of Game of thrones on IMDB.....this link......

Anyway, I thought this was interesting about how fans treat Lena Headey...
“Cersei Lannister (Lena Headey) was voted by fans as the series’ most hated character. Headey has said that she is often the victim of fans who direct their hatred towards her character to her personally. People frequently call her names both on-line and in public, and at fan conventions, she is more than often shunned. She claimed that during an autograph session at Comic Con, people were actually snatching their books from her hands to prevent her from signing it.”
I find that very telling because it shows that it takes very little to get someone to dislike a public figure, even if is entirely fictitious, just by how that figure is portrayed in the media whether it be news media or entertainment really controls how the public reacts. It explains a lot of how Trump gets so much hate while someone who is truly evil like Hillary is celebrated.
My understanding was that the same happened to the actress Alison Arngrim who played Nellie Oleson on “Little House on the Prairie”.
People would project their dislike of the character Nellie onto the actress. I seem to recall a piece of trivia that she was once hit in the head by a can of soda by a fan who disliked the way she (Nellie) treated Laura.
Jack Gleeson (actor who played Joffrey) was treated very badly by fans, too. He has retired from acting. I would guess that bad treatment by Game of Thrones fans is one of the reasons why.
