In fact I don't remember any player ever physically threatening ppl like that
Maybe you remember what Nalbandian did this year. On purpose or not, if Serena did that, she would be crucified. And I don't want to name all the players who were more than rude to lines people, chair umpires, but they never get as much shit as Serena does. Coincidence? I don't think so. She crossed the line, it was an awful behavior, but no, you can't describe her as a demon because of that. We all have outbursts, we are all classless now and then, but it looks like it's the worst sin ever only if it happens in front of camera.
Second of all, Serena has shown her classlessness waaaay more times than 2. She makes disrespectful or spiteful comments in her press conferences or interviews on a regular basis.
On a regular basis? Come on. She's simply honest, yes, she was mocking the ranking system and, yes, Safina didn't create that system, but she's entitled to her opinion.
And it's fine if you're ok with supporting classless ppl but that's not everyone's case.
It's also fine that you despise Serena, but it's not everyone's case and that's it.
By the way, I'm done with commenting on Serena and her outbursts in this thread, I'm not gonna be dragged into some endless discussion about Maria, Serena, racism and who knows what else. And that's how it mostly ends.
