I would argue that you ARE actually easily disgusted, if you find Nadal's behavior that abhorrent. He generally comports himself as a gentleman on and off the courts. I know that there's a lot of complaint about how slowly he plays, but as I have mentioned before, everyone praises him for his mental focus. I think his rituals and his slowness are about gathering that focus. You and others try to make it about gaming the other player. I don't agree with this, at all. I believe he plays slowly because it helps him think, plan, and make adjustments, which he does very well. There is a shot clock, and sometimes he gets called. But he's learning to work with it. So, let's face it, his pace of play is not "disgusting." There are rules for that, there are reasons that he plays "deliberately," I'd say. (And let's not forget that Djokovic can be a slow player.)
Bandage-Gate: You don't like the timing of when he it was bothering him, and took the time to rip it off. It didn't take that long. What about Federer going off the court v. Dimitrov for treatment on his neck, when he'd lost the 4th set? Where is the outrage? Something's bothering you, and you're losing so you want to try to fix it...is this a newsflash?
Here's the thing: there IS sometimes some disgusting behavior on-court done by tennis players. Kyrgios rings a lot of bells. Otherwise, screaming at umpires, throwing racquets, hitting umpires and lines people (Shapo/Nalbandian,) throwing coins gets mentioned, actually physically attacking the opponent has happened; racist comments have been made. Even Federer has been known to curse and throw racquets more than a few times. Djokovic came within inches of being defaulted when he nearly hit a linesman at RG, and I think that might have been the year he won it. Of all of these things, which of them is Nadal guilty of? Answer: He did get called for cursing once.
So, yes, I'd say you have a particular gag-reflex where Nadal is concerned, and it doesn't seem that he's earned your disgust. It comes down to the chicken-egg thing, right? If Nadal hadn't always been such a finger in Roger's eye, would he really bother you that much? Would there be this endless narrative created by Federer fans about what a Black Hat he is? A cheater? To me, it's clear why we keep massaging over the same small things...even years after they happened. You all whip yourselves into an endless frenzy, and including about falsehoods, and keep telling yourselves the same bedtime stories, because it suits your narrative.
