I know you're trying to be helpful and reasonable, Dude, but we do all expose our biases when we get in these arguments, and I will expose mine here, as well. It's very hard not to read unspoken agenda into these Fedal Wars posts, and hard not to group fans, even where some are more guilty than others. I know you're trying.
There is a phrase that I think gets folks riled up, and that is "match on his racquet." It implies superiority, and is used too freely, IMO. Funnily, I think that it is much more common for Roger's fans to claim the match on his racquet, and the rabid ones insist that all losses are down to Roger being crap. Rarely a nod to the winner, especially if it is Nadal. Now, that's the rabid ones, but you did just say above: "
Rafa is so great that the match is usually on his racket. Except when he's playing either another great player (Novak, Roger)...," which is a bit laughable, given his record over Roger. Do you see how that phrase is loaded and incites argument? Now, as I said, I would expose my own bias, by saying I hear it more from the Fedfan camp. But we peg what bothers us, so I'm not pretending no one says it from the other side.
What diminishes the conversation particularly is rummaging around in the old resentments of matches lost, piling on excuses (from both sides,) and refusing to acknowledge the absolute greatness of both Federer and Nadal. Many posters do acknowledge this, and debate appropriately. But the far wings of each camp are entrenched, and won't let a rude slight go by without an equally absurd retort. Even on this thread it was reduced to something like 'you didn't go to 7th grade,' and 'you didn't even go to kindergarten.' I'm not even making that up. Reasonable people, such as
@Federberg have decided that life is simply too short, and essentially quit the conversation altogether. That's a shame. There's no solution to trolling, and by that I mean hammering one's point, endlessly, regardless of points made in the discussion, only to further an agenda. Those who will have only one winner in the Fedal Wars will never see it differently, sadly.
