Nice cherry picking of facts and personality traits to suit your purpose.
Stoner a bad loser attitude or just unhappy with some of Rossi's moves - there's a difference. The helicopter shot that showed Rossi pushing Stoner to the edge of the track, more than once, on the start finish straight no longer seems to be on youtube or the net. More crude and dirty tactics than 'racecraft'. Stoner also refuted the suggestion in the post race interview that Rossi brake tested him at the corner he ran off at (sure as hell looked like it - he did it to Lorenzo at Barcelona) He simply said 'no - my mistake'. Yet he's a bad loser for that.
Stoner cracked under pressure? They made one mistake each in that race. Rossi got it hopelessly wrong at the top of the corkscrew and ran off track through going in too fast. He could have taken himself or both of them out. He was lucky and got away with it. Stoner got it wrong and ran off track but hit deep gravel which pulled the bike over. He didn't get away with it.
Rossi's charisma? - the charisma that saw him remain sitting on his bike in parc ferme, refusing to talk to anyone, refusing to remove his helmet and refusing to congratulate Lorenzo, because he was sulking after Lorenzo beat him in his home race. No foul play of cheap tricks from Lorenzo, he just beat him. A demonstration of the charisma of a good and sporting racer?
Rossi bitched and moaned about Elias' 'dangerous riding' after Elias beat him in the penultimate race in 2006. Bad loser or justified because of the way Elias was riding? - or purely hypocritical after the way he took Gibernau out at the last corner at Jerez. Next race Rossi 'cracked under pressure' and threw both his bike and the chance of the title down the tarmac at Valencia.
Laguna 2008 Rossi 'beat Stoner through racecraft' even though Stoner 'had the fastest bike' - why not mention that it was the worst handling bike. Laguna 2011 and 2012, the Ducati was still the fastest bike. Didn't notice it at the front end of the grid though.
Whichever situation from history you want to pick up on and criticise a rider for their behaviour at that time, yo can equally do the same for other riders. But as usual, you gloss over occassions when Rossi has been in those situations and instead concentrate on regurgutating them to deride the achievements and ability of any rider that had his measure.
Like someone else pointed out, wonder who it will be next year.
Can't wait to see Rossi's reaction if Marquez takes him off the track in a race - especially if Marquez justifies it with 'that's racing Valentino, that's racing'...
