Can everyone stop insulting Nadal in crude and childlike manners.
These are the main reasons as far as I can tell.
A: Potential Doping. There is no real evidence of this. Please stop from this until allegations become serious. By doing this you delegitimize all the results. If Nadal took the record I would rather it be fair than via doping. His doping would be worse for the sport so I don't know why you seem hopeful about it.
B: Style of Play. If you don't use a style that will allow you to win with millions of dollars on the line than you are simply an idiot. I know some of you are angry at the court speeds, but if so do you expect Nadal to skip slow tournaments. This is the directors fault not Nadal's. I bet you a million dollars that every other player on the tour would play like Nadal (except Djoker, Federer, Kyrgios and Tomic) if it led them to his success levels.
C: Going to Catch Federer: Perfectly legitimate reason to root against him it's all your heart, but that can be done respectfully.
D: Personality. He seems to be humble and nice and he has never broken a racket so I don't see a problem here. Sure has some eccentricities, but that doesn't make him a bad person.
E:Time Wasting. Really. Really. You can complain, but does this rise to the level of name calling. It has nothing to do with success and everything to do with his routine. I agree he should go faster, but you wouldn't care if Roger wasted time. That wouldn't be a big enough problem.
The only thing that could disprove my argument (that I can think of) is if doping allegations were proven, but as far as I can tell there is zero evidence besides the fact that he is muscular and lasts long times on the court. Have you ever thought that some people are better in this way than others. There is variance and the reason he is at the top is partly because he falls on the right end of the spectrum and has incredible competitiveness and the heart of a champion.
Even if all these things are disproven to you and you have great counter points there is still no reason to use crude language towards him.
