No, it's my opinion that Marc wasn't racing. If I had issue with no-one other than Jorge being able to race Rossi, I'd be complaining about Pedrosa (Aragon) and Iannone (PI) right? Again, it's my opinion that Marc was not racing and that's what I took issue with.
I can see why you eschew counter-arguments. So only riders who Rossi doesn't dislike or who you or he don't think dislike him at a given point in time can race him?
I know there is no point, but I will explain why your opinions , and Rossi's press conference claims, concerning the PI race were/are so ridiculous and bemusing, without going further into how murky Rossi's motives may have been, despite motive being the entire basis of your contentions regarding MM.
MM WON the race, against both Lorenzo and Rossi, both not only greats in historical terms, particularly your boy, but in great form and on a good bike , as evidenced by their current positions in the championship. To do this he had to ride superlatively well, not very arguably at a level beyond which anyone else would have crashed the bike given his fellow HRC rider, a rider historically no slouch and capable of dominating the next round, languished in 5th while MM "fixed" the race. He almost crashed himself earlier in the race which is how your boy caught up to him in the first place. You are arguing that not only should he be forced to do the impossible to the same degree at all times, but you or some of your cohorts also seem to be arguing that he can and should be compelled to do so by legislation enforceable by the stewards. It is very likely at least partly down to physiological factors/adrenaline etc and not entirely within his conscious control how far past the edge he rides at any given moment anyway. You may not have watched much racing, or if you have have not watched anyone except one rider, but it is hardly uncommon for riders to try harder against some riders than others anyway.
We then have the other factors which have been raised, fuel load, how his tyres were working, and his tactical assessments; he is absolutely allowed to control the pace when racing for position to suit his tactics or strategy. He may have been confident he could deal with Lorenzo on the last lap, but not so confident about Rossi or particularly Iannone with his straight line potential.
He did absolutely nothing untoward in terms of moves he made on anyone in the PI race. In particular, he beat Lorenzo, the rider he was putatively aiding, in the race. Had he got a 5 second lead, pulled up and let Lorenzo through, then raced Rossi (if he had been third) a la Sepang 2015, or as Rossi did Stoner at Laguna Seca1998, perhaps then you could call "race-fixing", although MM could possibly argue in that situation going by your recent contentions that he was justified because Valentino had irked him.
What seems "obvious" to me is that the problem for Rossi at this , the crux of the season, is that with Dani healthier, MM having adapted his riding, and the HRC bike possibly improved , there are now 3 riders , and sometimes 4 counting Iannone, who have pace and likelihood of completing the race which is threatening for Rossi, particularly given his weakness in qualifying and early in races.
