He fosters and encourages that behaviour.
I once saw a little interview with him where it was asked about the behaviour of some of his rabid fans on social media in regards to their treatment of other people on twitter who may express any form of criticism towards him.
His reply?......"Well they shouldn't mess with me".
He comes across as someone that isn't grown up enough to handle being admired as an idol. He's too thick (if the bit in bold is right) to realise that what he's saying could lead to serious violent behaviour.
