The difference between Elton John and so many of Hollywood's 'stars' clawing for attention is that Elton John has arrived.
He (Sir Elton John) was knighted in '98 by Queen Elisabeth.
That puts him is a recognition weight class so far above those in Hollywood groveling at the feet of the media for attention and praise, that he can be himself, and be amused by someone else's antics who is in the same recognition weight class as world figures go.
There is no obligation to craft his views to avoid being made a 'nonperson' in Hollywood, and no amount of pandering to the mediots will do anything to enhance his standing, which is secure.
