I don't hate any celebrities. I dislike a few, but I dislike them for valid reasons. Let's take Kristen Stewart as an example. She cheated on Robert Pattinson with the director of Snow White and the Huntsman. I don't like cheaters, therefore Kristen Stewart has Остаться в живых some of my respect.
I don't think it's right to hate celebrities. I don't think it's right to hate ANYONE. Because they are famous, nearly every detail about them is released to the public for the world to know. They're just as human as we are, and humans are prone to making mistakes. For that reason, and because of all our humanity, it is not ethical to hate a celebrity или anyone for that matter.
