Knetz will believe dating rumors or news but overdramatize it. They know idols date but they expect them to not get caught so they don't break their 'required' illusions about them.
ifans on the other end prefer to automatically disbelief rumors and even verified news, sometimes coming up with conspiracy theories; as if they were government plots. Basically they like to keep the illusion that their biases are virginal or just engage in LGBT relationships with each other.
The fact is idols date often, some date more than others. They SHOULDN'T be required to hide their dating to extreme degrees, but because of the fan culture they know it could affect their careers and give grief to their companies. Idols shouldn't be babied or thought of as too innocent for dating even one person. They are human beings like you. Just think, if you were a attractive and charming idol surrounded by attractive people, at the time of your life your hormones are raging, and the only thing you really need to do is give someone your KKT name. What would you be doing? The pressures of idol life are enough, they can probably find a lot of releases from stress through dating and being with people facing similar circumstances.
