See what happens online if you criticize any popular performer in any way. Watch the comments section if it's a blog, or see what people tweet or how they reply on Facebook. Almost immediately, somebody will accuse you of "sour grapes" or of being jealous.
Why is that? Why has it become impossible to express an opinion about a performer without being personally (and illogically) attacked? Why do fans take that opinion so personally themselves and feel they have to slam the writer?
