Everyone at this forum, and I mean "everyone" of us is a hater, whether we admit it or not.
Wrong. I don't hate any player of the tour. If I'm happy that a player lost, it's only because my favourite opponent won.
The player that irritates me the most is probably Sharapova, and basically any player who screams loud on big points. But that doesn't make me hate them, and I'm not happy to see them losing for that matter.
Each time I read a post that shows happiness at a player who lost just because the poster doesn't like the player, I find it completely stupid and despicable. I have no respect for any poster acting that way.
I think that if you enjoy tennis as a sport, you like every tennis player good enough to play on the tour. You may dislike the personality (what do we know about their personality anyway?), but you can still enjoy the game. You may also favour games to other games, but still as long as a game is good enough to be competitive, it's part of the sport and you cannot totally dislike it. It's my case.
So, whether you admit it or not, not everyone is the same. There are, actually, people a bit less stupid and a bit more mature than others on this forum.
