As for the Federer fanbase suffering the same type of scorn and accusations as the Nadal fanbase, if you truly are unbiased, you will realize they are not even in the same level. Doping, cheating, and all sorts of crap. Federer suffers ridicule because of the H2H and his crying in trophy ceremonies, but no accusations of the magnitude and viciousness with which radical Fen fanatics seem to enjoy attacking Nadal.
So yeah, I reiterate what I said in my previous post.
Doping accusations without proof are undeniable over the top. They have been made against Fed as well though. That said, for non-rational fans, who already hate Nadal to the core, there's something about his game that - more easily than Federer's game - lends itself to doping-accusations. I.e. the utter physicality of his game, the ability to run, run and then run some more and find his best level in the fifth or six hour of a match. And then go out there the next day and do it all over. Plus that vast difference between his results in the first half and the second half of the year.
To be clear - I'm by no means saying he's a doper. But for someone inclined to that line of thinking, it's not a massive step to take.
As for the 'cheating', that is a logical response to Nadal's (and Toni's) actions on the court. Rafa takes too much time between points, Toni coaches him illegally from the sidelines and has admitted as much and been fined for it. Now you may or may not think of this stuff as a big deal. But you cannot expect a fanbase from another player not to call him out on it (and when that happens, you have a bunch of Rafa fans pointing to the one or two instances where Fed might or might not have attempted to cheat)
Finally, you yourself (who's a rather classy fan for 90 % of the time
) has in this thread made a comment such as
"I was checking betting odds earlier and they are 3.45:1 that Princess will cry again if he loses."
To me, that's at the very least as offensive as calling a player, who match in and match out continuously breaks and bends the rules a cheater. As that is objective according to the facts at hand - just as well as Fed did cry after one of his Aus Open loses (I would heighten the odds though, this is only a semi).
For any fan of a particular player, the other fanbase will seem just as bad (if you can see the splinter in your own eye) or worse.
I personally get a whole lot more provoked by the Nadal fanbase, because they attack my favorite player and I suppose the vice versa is true. But I still personally regard the worst of the Fed and the Nadal fanbases as equally bad
If any one can say which fanbase is worse, it would have to be a truly neutral fan (and the two of us are neither), who spends enough of his or her time on tennis forums to have an idea.
Any idea of who could be a good judge? I don't.
