It’s well enough to say, ‘hey, I think Nicky screwed up my lap’; its quite another thing entirely to say, ‘hey, Nicky screwed up my lap on purpose, intentionally’ (which means he did that for some dubious purpose)…and say it publicly.
I am fairly sure that was not stoner's point though. His consistent argument is that this is a safety issue, and I believe it is about this for him and not about people screwing up his laps; I also believe he is correct in this view, if exaggerated with some of the specific incidents (I wouldn't necessarily baulk if someone said many of the incidents). Imo he is not saying that nicky is morally reprehensible and deliberately screwed up his lap, but rather that it wasn't accidental that nicky was going slowly on the racing line and hence in stoner's view constituting a safety risk.
This doesn't imply that I think nicky is morally reprehensible btw, just that he does not consider it to be as big a safety issue as stoner. The whole thing does not seem as big for the riders as it is for rossi fans currently bereft of other avenues to criticise stoner; my surmise as I have said previously is that they think stoner has a bee in his bonnet about all of this and don't take it very personally, perhaps also recognising that there is some basis in fact even if he exaggerates the matter.
