Fame always seems to come with a certain amount of privacy expense. Whether that's youtube/internet fame, movies/television fame, political fame... etc.
But in my opinion, regardless of who you are and how famous you are - there are certainly still lines that SHOULDN'T be crossed. My opinion is that anyone showing up invited at anyone's house and unwelcomingly invading someone's personal and private space is in the wrong.
Well known or not, I think every person has the right to draw a line and delineate what they desire to be their publicly accessible self and their private self. Just because I put certain pieces of myself out there for others to see and scrutinize as they wish, does not mean I am obligated to put any other pieces of myself out there if I do not wish. Famous people don't 'owe' anything to any fan or critic. They are still a person, just like anyone else, and I think yes, they absolutely should expect a certain amount of privacy and respect regarding that. I personally don't get at all the obsessed fanatical fans that will go absolutely bat shit crazy to see or meet a well known individual. It boggles my mind. Sure, there are authors and musicians and even actors /actresses, etc., that I would love to meet and have a beer and a chat with because I think they seem to be an interesting person. But would I got to any sort of extreme length to get that opportunity or jump up and down and cry at the site of them? Absofuckinglutely not. That behaviour is just bizarre to me. Foreign to me. Showing up uninvited to a celebrity's house seems, extreme, to me. I wouldn't want someone doing that to me regardless of how famous I was. I don't think that's an unreasonable expectation of privacy, regardless of your status. And I mean really.. wouldn't you think someone would have better things to do with their time than obsess over celebrities? This is an area I just don't understand about a large portion of my fellow humans.
But that's not, unfortunately, how many other people seem to see it. They feel it's their absolute right to know anything and everything they want about a person, simply because they are famous or well known. I disagree with that.
