I really don't mind Federer. I think he's truly a great player. I enjoy his matches - win or loss. And I don't think at all he is responsible for this cult like fanbase. It's the ordinary minded people who have the tendency to become all obsessed with celebrities/players for no good reason. I see it as an escapism. People don't like their own reality so they subscribe to those that aren't their own reality. It's a very nice escape for them.
Baron, for example, is really a level headed person but he too I feel is a bit too protective about Federer. I have a really good friend who's a big Federer friend but his obsession over Federer I find really unhealthy. There are also some serious Fedal fanatics out there.
