I don't think there is anything wrong or irresponsible with this tweet.
It is an outburst, just the way the so called fans had an outburst. The people who are playing the characters of this show so well, are ACTUALLY REAL PEOPLE who have feelings. They are NOT the characters they play. And "FANS" need to understand that.
These people are paid to their job. And their job is to portray a CHARACTER. And I think they are doing it brilliantly at such a young age. Fans need to understand that this is a SHOW. It is not real life. There is a thin line between loving a show and loving a show so much that you forget it is FICTION. The story is NOT written by the actors. They are doing what they are told to do.
I really feel bad for all the celebrities. It is the price they have to pay. As much as they are loved, it is incidences like these that they remember always. Fans need to be mature enough to understand that the ACTORS have feelings too.
